CHANGELOG
=========

v3.2.2
------

* Fix: Play 2.2 instrumentation in action methods

  In version 3.2.0 and 3.2.1, the Java agent failed to instrument calls present
  in a controller's action method. This means database calls, external calls,
  and custom instrumented calls within the action method were not being reported
  to New Relic. This bug has been fixed.
  
* Fix: Invalid exclusive time Errors with Play 2.2

  In version 3.2.0 and 3.2.1, the Java agent sometimes reported error messages
  to the newrelic log indicating an "Invalid exclusive time". This error
  has been fixed.

* Fix: Inaccurate async wait time with Play 2.x 

  In version 3.2.0 and 3.2.1, the Java agent reported an async wait time for
  Play 2.x transactions that was too large. This bug has been fixed.

v3.2.1
------

* Fix: Exceptions thrown from conflicting JAXB versions

  The New Relic Java agent now supports customers using any JAXB or Xerces 
  version. This bug was introduced in version 3.1.0.

* Fix: Usage of the newrelic.bootstrap_classpath system property

  In version 3.2.0, the newrelic.bootstrap_classpath system property caused
  an IllegalAccessError. That bug has been fixed. Note also that this system
  property has been deprecated and should not be used.

* Fix: Data collection for customers using the IBM JVM without WebSphere

  New Relic now supports customers using an IBM JVM without running 
  WebSphere. In this scenario, you must set the sync_startup flag set to
  true in the common section of their newrelic.yml.
  
  sync_startup: true
  

v3.2.0
------

* Glassfish 4 metrics for JVM Memory, Thread Pool, and Transactions

  New Relic now displays JVM memory, thread pool, and transaction metrics for
  Glassfish 4. To expose these metrics, please set http-service, transaction-
  service, and web-container monitoring within Glassfish to high.  To see the
  metrics in New Relic, go to Monitoring > JVMs.
  
* Decreased agent overhead for Play 2

  This version of the agent reduces the overhead that it incurs on Play 2.
  Play 2 users should upgrade for improved performance.

  In addition to general overhead improvements, New Relic has introduced a
  new setting to reduce overhead even more for particularly low-latency
  applications. Note that this setting will make the call info in Trace
  Details more generic.

  transaction_tracer:
    stack_based_naming: false

* Manually disable auto RUM instrumentation for specific pages

  For supported JSP engines, New Relic automatically adds RUM (Real User
  Monitoring) elements to the response HTML.  If you like auto-RUM, but do
  not want to apply it to all pages, you can now disable it for select pages.
  The configuration property disabled_auto_pages in the browser_monitoring 
  section can now be used to disable auto RUM instrumentation for a comma 
  delimited list of pages. For example,

  browser_monitoring:
    disabled_auto_pages: page1.jsp, page2.jsp

* akka.actor.ActorKilledException is now ignored by default

  The ActorKilledException is commonly thrown in Play applications as a
  control mechanism in normally functioning applications.  In previous
  versions, this exception inflated the reported error rate.  These 
  exceptions are now ingored by default. You can override the default
  ignore_errors list to provide your own exceptions or to omit the
  ActorKilledException.

  error_collector:
    ignore_errors: some.other.MyException

* New Relic reports host capacity information

  New Relic now reports physical CPU cores, logical CPU cores (hyperthreads),
  and physical memory. On non-Linux platforms, the agent runs a subprocess
  to retrieve this information.  To see the info in New Relic, go to
  Settings > Environment > Environment Snapshot.

* Report JVM name and revision to New Relic as part of JVM description

  Recording the JVM name in addition to the vendor allows differentiation 
  between different JVMs from the same vendor.  To see these values in New
  Relic, go to Settings > Environment > Environment Snapshot and look for the 
  "Java VM" and "Java VM Version" settings.
  
* Fix: Support for Play 2.2

  Web transactions were not being correctly captured under some circumstances
  for Play 2.2 applications.  Web transactions are now correctly reported.
  Also note the change in command line syntax as of Play 2.2:

  https://docs.newrelic.com/docs/java/play-installation-for-java
  
* Fix: Background tasks created by an @Trace annotation with a 'metricName' element
  did not show up in the New Relic UI.


v3.1.0
------

* Percentiles and Histograms

  The Java Agent now captures data that provides percentile and histogram
  views in the New Relic UI.

* JAX-RS annotation instrumentation

  The Java Agent now instruments and names web transactions based on
  javax.ws.rs annotations.

* JAX-WS instrumentation

  The Java Agent now instruments methods on classes that are marked with the
  javax.jws.WebService annotation.

* Fix: In some cases, agent had excessive overhead on Spring AOP apps

  The agent should now perform well for any Spring AOP application.

* Fix: Play Framework instrumentation was ignoring the ignoreTransaction call

  The Play Framework 2.x instrumentation now honors the New Relic API
  ignoreTransaction call. 
  
* Fix: Potential memory leak when app continually creates ClassLoaders

  The Java Agent now handles applications where ClassLoaders are
  continuously created.

* Fix: Agent zip distribution did not include the API source jar

  The newrelic-api-sources.jar is now included in the zip file.


v3.0.1
------

* Fix: Issue at startup with JBoss and Glassfish

  An issue in the 3.0.0 version caused startup of some versions of JBoss
  and Glassfish to fail. This version fixes that issue.

* Fix: RUM not auto-instrumented for JSPs

  The Java Agent should auto-instrument RUM header and footer in JSPs
  when using the Jasper engine. This did not work in 3.0.0. This version
  fixes that issue.

v3.0.0
------

* Spring AOP instrumentation

  This version instruments any call that passes through an AOP pointcut that
  you have declared in your Spring application. This gives your additional
  insight into the call time of key Spring beans.

* Performance Improvements

  This version contains optimizations that reduce agent overhead. 

* Fixes: Hibernate improvements

  In this version, we provide more consistent detail into Hibernate calls
  across supported version of Hibernate (3.3 - 4.2).

* Fix: Removed need for WebSphere SSL work-around

  Previous versions sometimes required a work-around when using WebSphere.
  This version removes the need for a work-around.

* NOTE: Requires Java SE 6 or 7

  Java Agent 3.0 requires Java SE 6 or 7. At signup or in your Account Settings
  page, you have the option to download a version of the agent that works with
  Java SE 5.


v2.21.4
-------

* Fix: Metric Grouping Issue with Netty
 
  The request URL was referenced in some metric names, causing
  Metric Explosion. The URL is no longer included in the metric name.

* Fix: Make Cookie parsing more robust when running on Netty
 
  Cases where the Cookie header was malformed were causing exceptions to be thrown.
  Agent now makes a better effort to capture the individual valid parts.

* Fix: Agent could not connect to New Relic in non-DNS environments

  Fixed an issue which caused the agent to only be able to connect to New Relic in
  environments where DNS was used for hostname resolution.
  
* Fix: In 2.21.2 and 2.21.3 an @Trace annotation ignored the transaction for Apdex 

  An @Trace annotation on a method called in a web transaction had
  the side-effect of ignoring the transaction for calculating the Apdex score.

v2.21.3
-------

* Fix: Agent did not run with J2SE 5.0 (aka JDK 1.5)

  Release 2.21.0 - 2.21.2 did not run correctly on J2SE 5.0. On startup,
  the agent reports:

    Unable to start New Relic agent: java.lang.UnsupportedClassVersionError:
    Bad version number in .class file 

  If you are running J2SE 5.0, please update to agent version 2.21.3.


v2.21.2
-------

* Fix: Longer application startup time

  Release 2.21.0 introduced an issue that could cause application startup
  to be slower than in previously releases. This fix returns application
  startup time to normal.

* Fix: File location changes

  Release 2.21.0 introduced a change to file locations within the
  newrelic zip file. This fix reverts the locations to what they were
  previously.


v2.21.1
-------

* Fix: In 2.21.0, calls to NewRelic class can cause NoClassDefFoundError

  In 2.21.0, if your application calls the NewRelic class and does
  not include the newrelic-api.jar, the application would throw a
  NoClassDefFoundError. With this fix, the separate newrelic-api.jar is
  not required. However, it is recommended that your application include
  the newrelic-api.jar so that calls to the NewRelic API resolve with or
  without the agent installed.


v2.21.0
-------

* X-Ray sessions

  Adds support for X-Ray sessions.  An X-Ray session collects
  Transaction Traces and a thread profile for a Key Transaction.

* Fix: In 2.20.0 an @Trace annotation ignored the transaction for Apdex 

  An @Trace annotation on a method called in a web transaction had
  the side-effect of ignoring the transaction for calculating the Apdex score.

* Fix: HTTP status code for Errors 
    
  If the HTTP status code for a web transaction was less than 400, the HTTP
  status code reported in the error was 500.  The actual status code for the
  web request is now reported.
    
* Fix: Spring exception handling
    
  The Exception argument in the Spring DispatcherServlet processHandlerException method
  was reported as an Error with an HTTP status code of 500.  The actual status code
  in the HTTP response is now reported.
    
* Fix: Reading Post Parameters for Resin 3

  Prior to this fix, post parameters in Resin 3 were always read using the 
  default properties even if the application tried to read the post parameters 
  using non-default properties or by just grabbing the request input stream.

* Fix: JVM Tab Metrics Not Showing up for Tomcat Applications

  Prior to this fix, if the service name in service.xml was not Catalina, then
  metrics would not appear under the JVM tab. Additionally, if you are using an 
  embedded Tomcat 5/6, metrics should now appear under the JVM tab.

* Fix: Improved compatibility with Java 1.5

  In the custom xml validator, there were references to String.isEmpty() which
  was not available until Java 1.6.  Those have been removed.

* Fix: Reducing DNS problems by not automatically adding '.' to the domain name

  By default the '.' is included. But if changed, then the '.' won't be added.

* Fix: JVM tab metrics showing for all Applications In JVM

  Metrics under the Thread, Session, and Transaction tabs used to only appear
  under the main application. The data will now be shown for all applications
  running in the specific JVM.

* Fix: Using a Proxy now works with SSL Enabled 

  In prior releases proxy authentication would fail when SSL was enabled.
  We now do proxy authentication using the java.net.Authenticator.
  
* Fix: Akka error reporting

  If an actor throws an exception or the message times out, an error is reported.
  Previously, no error was reported.
  

v2.20.0
-------
* Glassfish 2.1 JVM Tab

  The JVM tab will now show thread, session, and transaction metrics for 
  Glassfish 2.1.
  
* Fix: Solr Cache Metrics 

  The solr cache metrics do not appear with versions 2.18 and 2.19
  of the agent. This has been fixed and all solr metrics should now appear.
  
* Fix: NullPointerException in New Relic Logs When NewRelic API called 

  In certain circumstances, a call to a method on the NewRelic class can
  generate a NullPointerException in the agent logs. It does not cause a
  NullPointerException in your application.
  
* Fix: Support Custom Extension XML File for WebSphere with JRE

  Prior to this fix, an attempt to use a custom extension XML file with a IBM JRE
  would lead to a ClassNotFoundException.

v2.19.1
-------

* Fix for 2.19.0 known issue:  Play now captures GET and POST
  parameters correctly if `capture_params` is enabled.

* Disabled overly ambitious instrumentation used to time template rendering for Play 2.
  Resulted in unintended classes being instrumented.

v2.19.0
-------

* Play 2 Instrumentation

  Provides insight into Play 2.x Java and Scala applications. Adds
  instrumentation to Netty server, Akka actor calls, Scala Promises and Futures,
  and the WS API calls.

  Known issue: Request parameters are not captured properly
  even if `capture_params` is enabled.

* Support added for Jetty 9 (tested on 9.0.0 through Jetty 9.0.3).

* Fix: Agent can cause java.lang.VerifyError on code compiled with Java 7

  In certain cases, if your application code or third party libraries are
  compiled with Java 7, you may get a java.lang.VerifyError. This fix allows
  the agent to work correctly in those cases.

* Fix: The Java Agent detects status codes for Apache Felix correctly by default.
  The property take_last_status is now deprecated.

v2.18.0
-------
* New metrics are displayed under the JVM tab

  While the metrics displayed differ between application servers, common
  metrics include loaded class count, active thread count, active thread count
  per thread pool, active session count per application, and active
  transaction count. In order to see these metrics, JMX must be enabled on
  your app server.

* Fix: When naming transactions, the property `enable_auto_transaction_naming`
  should be honored

  There was an issue where transactions using the Spring Framework were
  ignoring the property.

* Fix: Strip query string from HTTP Referer

  Query strings can potentially contain sensitive information. To prevent that
  data from being sent to New Relic, only the host and path portion of the
  referer are captured.

v2.17.2
-------
* Fix: Fixed bug in which application code can throw NoSuchMethodError

  In some cases, application code was throwing an exception

   ```
   java.lang.NoSuchMethodError: java.lang.Boolean.valueOf(B)Ljava/lang/Byte; 
   ```

  This usually occurred when calling a ResultSet implementation.

v2.17.1
-------
* Fix: Reverted transaction naming change on ColdFusion, introduced in 2.17.0.

  That change caused issues with certain modes of ColdFusion.

v2.17.0
-------
* Agent reports JDBC ResultSet query time

  This change gives you deeper insight into your database time by displaying
  ResultSet processing time in aggregate metrics and transaction traces.
  
* Fix: Avoid retransform exception on IBM JREs

  In some IBM JRE versions, the agent logged an INFO level exception and did not
  instrument select classes. This fix allows these classes to be instrumented
  properly.

* Adds a stack trace in a transaction trace for all methods taking longer than
  stack trace threshold.  This differs from 2.16 which only provided stack
  traces for a limited number of methods.

* Better transaction naming on ColdFusion
  * The CPU burn reported for an asynchronous app is wrong.
  * Application code in AsyncProcessing should be attributed to wait time

* Fix: Agent now works with Jetty 9

v2.16.0
-------

* Adds a stack trace in a transaction trace for methods taking longer than
  the stack trace threshold setting (in seconds).
  
    transaction_tracer:
      stack_trace_threshold: 1.0

* Cross Application Tracing support for HttpURLConnection.

  Adds request and response headers to external calls using the
  HttpURLConnection library to provided better performance data
  when calling applications monitored by other New Relic Agents
  (Java, .NET, and Ruby, with others coming soon).

* Fix: Cross Application Tracing does not correlate consistently when using
  WebSphere, WebLogic, Resin, and Glassfish.
 
  Cross Appplication Tracing did not correlate calling and called applications
  when the HTTP response was large.

* Queuing time more broadly supported.

  The 'X-Queue-Start' and 'X-Request-Start' request headers for Heroku and other
  front-end web servers are interpreted and reported.  Previously, queuing time
  was not reported for Heroku.
  
* Adds a config setting to turn off class transforming after the given number
  of seconds. This is a work-around for an Oracle JVM bug that in rare cases 
  can cause native memory leaks.

    class_transformer:
      shutdown_delay: 3600
  
v2.15.1
-------
 
* Fix: Cross Application Tracing does not correlate consistently when using Tomcat 6+
 
  Cross Appplication Tracing did not correlate calling and called applications
  when the called application ran in Tomcat 6 or later and the HTTP response was
  greater than about 7k.
 
v2.15.0
-------

* Cross Application Tracing

  The Cross Application Tracing feature adds request and response headers to
  external calls using the Apache HttpClient libraries to provided better
  performance data when calling applications monitored by other New Relic
  Agents (Java, .NET, and Ruby, with others coming soon).
  
  The 2.14.0 release links aggregated data across applications. This release
  also links transaction traces.
  
  The configuration setting introduced in 2.14.0 to enable/disable Cross
  Application Tracing in newrelic.yml has changed. The old setting:
  'cross_application_tracing: true' is deprecated. The new setting is
  
  cross_application_tracer:
    enabled: true
    
  The default setting is true. Set to false to disable Cross Application
  Tracing.
  
* Instrumentation added for the AmazonS3Client version 1.x

  The New Relic Agent now offers support for version 1.0 to current of the
  com.amazonaws.services.s3.AmazonS3 interface. 

* New Relic Java Agent support a daily roll over log

  To roll over the agent log every day, set the property log_daily to true.
  Set the property log_file_count to the number of day logs you would like to
  keep.
  
* New Relic Java Agent now communicates with New Relic via HTTPS by default rather than HTTP

  If you have an existing installation and wish to use HTTPS to communicate
  with New Relic, edit your newrelic.yml file to include
  
  ssl: true
  
  in the common section. We recommend this for existing customers in order to
  improve the security of your communications with New Relic.
  
* Java Agent installer improvements

  The Java Agent installer now supports JBoss 7.x AS and JBoss 6.x EAP in
  standalone mode. Instructions for manually installing the Java Agent on
  JBoss 7.x AS and JBoss 6.x EAP can be found at
  https://newrelic.com/docs/java/installing-the-java-agent-on-jboss
  
* Fix: Default hostname reported

  This release reverts the change in 2.14.0 that effected the way that the
  hostname is reported. With this release, the agent reports the default
  hostname rather than short form in order to correlate with New Relic server
  monitoring.
  
* Fix: Web transactions naming in Spring MVC version 3.x

  This bug caused customers using Spring 3.0.1 and above to often have web
  transactions named by the servlet rather than controller method. This has
  been fixed such that a separate metric is created for each controller
  method.

  
v2.14.1
-------
 
* Fix: Application errors using java.net.HttpURLConnection.
  The bug, introduced in 2.14.0, could cause errors in code that uses java.net.HttpURLConnection.
  Possible errors could occur in XML parsing, incorrect http response status, or BeanCreationException in Spring. 
  As part of this fix the agent does not add a 'X-NewRelic-ID' header to outbound requests using java.net.HttpURLConnection.


v2.14.0
-------

* Fix: New Relic includes property take_last_status to only grab the final http status code.

    By default, New Relic reports any error status code. However, when this property is set to true, only
    the last http status code will be reported. This property should be set when using Apache Felix.

* Fix: New Relic now correctly patches Apache Felix ClassLoaders.

* Fix: Time will now display correctly for the first hour of the day when using log4j.

* Fix: RUM header was missing a semicolon at the end of the last statement.  Some browsers prefer semicolons everywhere.

* Adds a 'X-NewRelic-ID' header to outbound requests using the Apache HttpClient or HttpURLConnection libraries.
  This change helps improve the correlation of performance between services in a service-oriented architecture for a forthcoming feature.
  In the meantime, if you wish to disable the header, set 'cross_application_tracing: false' in newrelic.yml.
  
* Fix: Java agent now reports hostnames consistent with the output of "hostname -s" to match all other agents

* Add report of physical server memory (in addition to JVM memory) on Unix/Linux machines


v2.13.0
--------

* Agent can be configured to not send JVM arguments to the New Relic server

  The property send_jvm_props can be set to false, which will cause JVM arguments to no longer be sent to the server. Use this setting if you set sensitive system properties on the command line.
 
* Agent reports full URL in external service calls for transaction traces

  The agent now will provide the full URL if available in transaction traces for external calls.
  
* Fix: ResinServletTracerFactory no longer causing SkipServletTracerFactory errors

  When hitting the ResinServletTracerFactory inside a transaction, a SkipServletTracerFactory excetion will no longer be thrown.
  
* Agent logging improvements

  We have improved the clarity of logging messages, adjusted logging levels to be more appropriate, and increased logging performance.
  

v2.12.0
-------
* Agent reports jars used by applications to the Environments tab in the UI

  The Environments tab in the New Relic UI now shows the jars used by your application.

* Fix: In certain cases, auto-RUM of JSP broke HTML

  An angle-bracket in quotes in a META tag causes the agent to produced invalid HTML for JSP. The agent now produces valid HTML for this case.

* Fix: Key Transaction ApdexT value was not used

  In v2.10 - v2.11, the application-level ApdexT value was used for Key Transactions rather than the ApdexT for the Key Transaction itself. In this release, the ApdexT for the Key Transaction is used as designed.

* Fix: With OC4J using PolicyClassLoader, no metrics were displayed

  In the case where OC4J uses the PolicyClassLoader, the agent generated a java.lang.StackOverflowError in the log and did not provide metrics. In this release, the error does not occur.

* Fix: External metrics for HttpClient included port if host was an IP address

  In the case where an external service call used HttpClient with an IP address rather than a hostname, the port number was also included. In this release, the port number is not displayed.

  * More metrics available in Custom Dashboards


v2.8.0
  * Supports basic proxy authentication for the case where there is a proxy server between the agent and the Internet. 
    The configuration uses proxy_user and proxy_password settings.
