Java agent v3.7.0

Download this agent version

Notes

  • Flexible capturing of attributes

    The Java agent offers the ability to fine tune the attributes being sent to New Relic. Please see our docs site for more information on configuring attributes: https://docs.newrelic.com/docs/java/java-agent-attributes

  • Agent-Side High Security Configuration

    If your account is set to high security in the New Relic UI, you must add the following to your local newrelic.yml configuration file:

    high_security: true

    Without this property, the agent will stop collecting data when high security is enabled in the New Relic UI. See https://docs.newrelic.com/docs/subscriptions/high-security

  • Discovery of hostname reported to New Relic

    If New Relic reports an IP address for your hostname, you can now control whether the host name is an IP version 4 or 6 address by setting the following property in your newrelic.yml configuration file:

    process_host:
    ipv_preference: {4 or 6}
  • Improved JMX metric naming

    You can now set the metric name when configuring JMX metrics through a custom yaml file using the property "root_metric_name". Note, all of the JMX metrics will still be prefixed with "JMX" and end with the name of the attribute. See https://docs.newrelic.com/docs/java/custom-jmx-yaml-examples

  • Fix: Naming of CGLib classes

    CGLib auto generated classes with Spring resulted in poor metric names. The agent now excludes the random part from the name.

  • Fix: JMS transaction naming

    JMS onMessage instrumentation now uses a lower priority for naming transactions and honors the enable_auto_transaction_naming config.

  • Improved Jetty coverage

    Jetty versions 9.04 through 9.06 were not instrumented. This has been fixed.

  • Fix: Potential memory leak from database calls

    In some cases when database work is performed outside of a New Relic transaction, a memory leak could occur. This bug has been present in the agent since 3.5.0.

  • Fix: VerifyError can occur when using Nevado JMS.

Java agent v2.21.6

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

Note: 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 agent.

The 3.x agent works with Java SE 6 and 7. If you are using Java SE 5, this is the release for you.

  • Fix: XML entity expansion with non-SSL connection to New Relic

    Fixed an XML entity expansion vulnerability that only occurs when the agent is configured with ssl: false; the default is true. The agent already has other protection against unauthorized entity expansion. This fix is an additional layer of protection.

Java agent v3.6.0

Notes

  • Enhanced XML for custom instrumentation

    The custom XML xsd has been enhanced to support the instrumentation of interfaces, subclasses, and method annotations. These enhancements give you much more flexibility to identify transactions and add monitoring of components without changes to your source code.

  • Fix: Agent could cause VerifyError

    In specific cases, the agent could cause verification errors.

  • Fix: Embedded Jetty instrumentation

    Starting with the 3.3.1 agent, transactions were not reported for some configurations of embedded Jetty.

  • Fix: Exceptions incorrectly reported

    In some cases exceptions were reported even if configured to be ignored.

  • Fix: Embedded Tomcat not reporting JMX Builtin metrics

    In newer versions of embedded Tomcat the agent wasn't collecting JMX metrics properly.

  • Fix: Apache HttpClient 4.3 not consistently reported

    The Java agent now instruments Apache HttpClient 4.3 calls, including the new call patterns introduced in 4.3.

  • Fix: RESTEasy transactions

    In certain instances, transactions between applications were not getting linked correctly when RESTEasy was used.

  • Fix: JBoss 7 port not reported correctly

    The port was not reported correctly for some JBoss users.

  • Fix: Auto-RUM bug

    Starting in version 3.5.0 of the Java agent, in rare cases Auto-RUM could cause the New Relic footer script to be placed within a script tag.

  • Fix: Errors not reporting with some versions WebSphere 7.0

    In some Fix Packs of WebSphere 7.0, the agent did not report errors properly.

  • Fix: Agent works properly inside a folder with + in the path

    The Java agent did not initialize properly when in a folder with a + character in the pathname.

  • Fix: Agent HttpClient logging

    The Agent's HttpClient was writing to the app server's log when it discovered a log4j appender.

  • Fix: Inconsistent State with Play 1.2.x

    In some cases the agent was logging an "Inconsistent state!" message and not reporting a transaction.

  • Fix: Invalid errors for Stripes

    The Agent was erroneously reporting spurious 404 errors for web apps using Stripes.

  • Fix: Hanging threads in the Agent with SQL Prepared Statements

    Under rare circumstances, threads could hang in the Agent when an application with multiple threads made heavy use of SQL Prepared Statements.

  • Fix: Request queue time was incorrect for some versions of nginx

    Nginx fractional second header values for queue and server start times are now parsed correctly.

  • Fix: XML entity expansion with non-SSL connection to New Relic

    Fixed an XML entity expansion vulnerability that only occurs when the agent is configured with ssl: false; the default is true. The agent already has other protection against unauthorized entity expansion. This fix is an additional layer of protection.

  • Fix: In rare case, agent can cause application thread to hang

    Under rare circumstances, an application thread could hang when an application with multiple threads made heavy use of SQL Prepared Statements.

Java agent v3.5.1

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: Auto-RUM bug

    Starting in version 3.5.0 of the Java agent, in rare cases Auto-RUM could cause the New Relic header to be placed within a script tag. This bug has been fixed.

  • Fix: In rare cases, agent stops reporting

    In rare cases, the Java Agent hung on socketRead while performing an SSL handshake and would not report data until JVM restart. This bug has been fixed.

  • Fix: Occasionally missed web transaction when using ResultSet

    In version 3.5.0 of the agent some transactions that use a JDBC ResultSet were missing in the UI. The agent log would show an "Inconsistent State" error. This bug has been fixed.

  • Fix: X-Ray Sessions bugs.

    X-Ray Sessions sometimes returned no transaction traces. A memory leak with X-Ray Sessions when many sessions were run was also fixed.

March 5, 2014
Java agent v2.21.5

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

The 3.x agent works with Java SE 6 and 7. If you are using Java SE 5, this is the release for you.

  • PostgreSQL explain plan bug

    There was a PostgreSQL bug that allowed parameters to be sent in explain plans under some circumstances. To avoid this issue, the New Relic agent now does not report explain plans for PostgreSQL.

  • Agent no longer supports obfuscation of individual fields

    Previous versions of the agent allowed an obfuscatedsql_fields option to select specific field names to obfuscate when record_sql: raw. We have discovered rare cases in which this feature would not mask SQL parameters correctly, so we have removed the configuration option. Now, if obfuscated_sql_fields is set, the setting of record_sql: raw is ignored and _all fields are masked.

  • Fix: SQL parameter obfuscation didn't work if the parameter value contained a newline

    The record_sql: obfuscated config setting did not properly mask parameters when it included a newline character. This bug has been fixed.

  • Fix: Private trust store location for use_private_ssl flag

    The 2.21.4 agent did not properly load a private trust store used with the use_private_ssl flag. This bug has been fixed.

Java agent v3.5.0

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

  • New Relic supports WildFly 8.0

    The Java Agent now provides instrumentation for WildFly 8.0. You will see the same great visibility into your web transactions, app server stats, and frameworks that you have with previous versions of JBoss.

  • Fix: PostgreSQL explain plan bug

    Fixes PostgreSQL bug that allowed parameters to be sent in explain plans under some circumstances. Parameters are now masked prior to sending when explain plans are enabled (explain_enabled: true) and record_sql is set to 'obfuscated'.

  • Fix: SQL parameter obfuscation didn't work if the parameter value contained a newline

    The record_sql: obfuscated config setting did not properly mask parameters when it included a newline character. This bug has been fixed.

  • Agent no longer supports obfuscation of individual fields

    Previous versions of the agent allowed an obfuscatedsql_fields option to select specific field names to obfuscate when record_sql: raw. We have discovered rare cases in which this feature would not mask SQL parameters correctly, so we have removed the configuration option. Now, if obfuscated_sql_fields is set, the setting of record_sql: raw is ignored and _all fields are masked.

  • Fix: In some cases, an agent could fail to reconnect to New Relic

    Fixed several issues that in rare cases could cause the agent to cease reporting data until JVM restart.

  • Fix: Transaction name specified in XML configuration was being ignored

    In some cases transaction names set in XML files in the extensions folder were being ignored. This bug has been fixed in this release.

  • Fix: Jetty 9.1 transactions were not showing up in 3.3.x or higher agents

    Starting with the 3.3.1 agent, customers were not seeing transactions from Jetty 9.1. This bug has been fixed.

  • Fix: Websphere 7.0 was not being instrumented

    Starting in agent version 3.3.0, WebSphere 7.0 was not being instrumented. This bug has been fixed.

  • Fix: Solr tabs in UI not always appearing

    If you are running a Solr application and not seeing any tabs, please update to this version.

Notes

  • Fix: In some cases, Play 2.2 didn't report transactions

    When a chain of promises resolved, specifically using Future.flatMap(), lingering promises prevented the transaction from completing, in which case the transaction wouldn't be reported for the app. This is now tracked correctly.

  • Fix: Improved performance when instrumented code is not running in a transaction

    Avoids unnecessary work when code instrumented by the Java agent is not running in the scope of a transaction.
