Java agent release notesRSS

April 11, 2013
Java agent v2.17.0

Important

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes

  • 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

Important

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes

  • Adds a stack trace in the transaction trace for slow methods.

    This change provides additional insight into your slowest transactions.You can adjust how slow a method is before it generates the stack trace by setting stack_trace_treshold (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 frontend web servers are interpreted and reported. Previously, queuing time was not reported for Heroku.

  • Work-around for Oracle JVM bug that in rare cases causes a native memory leak

    In rare cases, the Oracle JVM can leak native OS memory (not heap space) when classes are intercepted by the agent. This setting turns off interception of classes that are loaded after the given number of seconds. The agent will continue to monitor classes loaded before this time.

    class_transformer:
    shutdown_delay: 3600

Java agent v2.15.1

Important

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes

  • 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.

February 28, 2013
Java agent v2.15.0

Important

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes

  • 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.

February 15, 2013
Java agent v2.14.1

Important

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes

  • 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.

February 8, 2013
Java agent v2.14.0

Important

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes

  • 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

January 16, 2013
Java agent v2.13.0

Important

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes

  • 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.

December 6, 2012
Java agent v2.12.0

Important

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.

Notes

  • 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 breaks HTML

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

  • Fix: Key Transaction ApdexT value not used

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

  • Fix: With OC4J using PolicyClassLoader, no metrics displayed

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

  • Fix: External metrics for HttpClient include port if host is an IP address

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