Java agent v2.21.7

January 8, 2015Download

Fixes

Important

This is a bugfix release for the legacy Java SE5 version of the agent. Unless you are a Java SE5 user, use the latest version of the New Relic Java agent.

  • Fixed an issue that in rare cases could cause the agent to cease reporting data until JVM restart.

Known issues

  • X-ray sessions sometimes return no transaction traces. Many x-ray session runs can cause a memory leak.

  • Play framework

    • Higher overhead with Play 2 than later releases.
    • Does not work properly with Play 2.2
    • Counts akka.actor.ActorKilledException as an error.
    • Play transaction does not complete until timeout expires
    • When using Play, ignoreTransaction call does not take effect
  • In some cases running Weblogic, the Java agent fails certificate validation when connecting to New Relic. This may require a workaround.

  • This release contains some inconsistencies in the instrumentation of Hibernate across versions.

  • This release requires a workaround to use SSL with WebSphere.

  • Potential memory leak when app continually creates ClassLoaders.

  • Rare memory leak if agent does not report to New Relic for an extended period.

  • When running IBM JVM without WebSphere, you must set the sync_startup flag set to true in the common section of newrelic.yml: sync_startup: true.
