    The following notes describe 4.5.x updates to the Java Agent. You can find resolved issues on 4.5.x Resolved Issues by Month.

    If an artifact has been updated, the version number of the updated artifact and its availability date are listed below. The version number corresponds to that shown on the download portal (http://download.appdynamics.com).

    The most recent releases appear at the top of the page.

    4.5.19 Updates

    Version 4.5.19 – February 20, 2020

    Enhancements
    • The AdoptOpenJDK is added to the set of Java runtimes explicitly certified with the Java Agent. Learn more.
    • Java Agent can now run without the jdk.jcmd module for the Java version 9 and later.
    • You can enable business transaction correlation using SOAP:Header with WebLogic, WebSphere, and Tibco implementations. The SOAP header is an alternative to the default correlation via HTTP headers. Learn more.

    4.5.18 Updates

    Version 4.5.18 – January 20, 2020

    Enhancements
    • The Java Agent now supports OkHttp versions 3 and 4 for the synchronous and asynchronous cases.
    • You can enable business transaction correlation using SOAP: Header with Spring WS implementations. The SOAP header is an alternative to the default correlation via HTTP headers.
    • Agent API: Two new APIs have been introduced, one for renaming a synchronous transaction and another for naming a transaction using servlet. Learn more.
    • An 'instrumentation SDK' has been provided that supports the use of the APIs. This iSDK allows users to create custom instrumentation to apply to the code in their application, therefore avoiding the need to make development changes to instrument the code. Learn more.
    • Agentless Analytics now supports license rules configured in the Java Agent version 4.5.18 and later. 


    4.5.17 Updates

    Version 4.5.17 – December 13, 2019

    Enhancements
    • The Java Agent now blacklists the use of several classes and methods for getter chains. Learn more.
    • For OSB, WSDL and SOAP are now web service entry points. 
    • The Java Agent now marks business transaction errors that originate from an OSB entry point.

    4.5.16 Updates

    Version 4.5.16.28759 – November 15, 2019

    Enhancements
    • The Java Agent now supports Micronaut version 1.1.0. 
    • You can enable business transaction correlation using SOAP:Header with Axis 2 and JAX-WS implementations. The SOAP header is an alternative to the default correlation via HTTP headers. 
    • You can collect Transaction Analytics data from the Java Agent without the need for a dedicated Analytics Agent. This feature is available with the 4.5.16 Controller and 4.5.16 Java Agent. Learn more in Application Analytics Notes
    Known Issue

    Transaction Analytics without an Analytics Agent is automatically enabled for SaaS Controllers with Java Agent 4.5.16 and later. If you deploy Analytics to multiple nodes, you may not receive Transaction Analytics data. AppDynamics recommends that you do not upgrade to Java Agent 4.5.15 and later if you are running multiple nodes. If you have already upgraded your deployment, contact AppDynamics Support to downgrade. 

    4.5.15 Updates

    Version 4.5.15.27926 – October 17, 2019

    Enhancements

    The Java Agent now:

    • Supports MongoDB Reactive Streams Driver, versions 1.3-1.12.
    • Detects access to MongoDB via MongoDB Async Java Driver versions 3.4-3.11, using asynchronous APIs.
    • Filters out snapshot segments whose duration is below a configurable threshold (5ms default) and does not make any exit calls to aid snapshot usability.  
    • Adds Push Promise support for Java HTTP Async Client. Threads executing push promise handlers will be correlated with the business transaction within which the associated HTTP request initiated.
    • Supports JDK13 with one 'Known Issue' (see below). 
    Known Issues

     When the 4.5.15 Java Agent runs on JDK12 or JDK13, it may cause the JVM to crash. To prevent a JVM crash, set the following property:

    • appdynamics.agent.prefer.retransformClasses=true

    This issue has been reported to Oracle and assigned Issue ID JDK-8232997.

    4.5.14 Updates

    Version 4.5.14.27768 – September 19, 2019

    Enhancements
    • The Java Agent now supports Jboss EAP 7.x
    • Support has been added for Mule 4.2.0 and 4.2.1.

    4.5.13 Updates

    Version 4.5.13.27526 – August 27, 2019

    Enhancements
    • Added support for Akka 2.5 for HTTP
    • Added OpenTracing support
    • Added support for collection of cross-app BT-BT metrics, disabled by default controlled by disable-service-monitoring-metrics node property
    • By default, AppDynamics excludes SSLv3 and TLSv1protocols due to the known vulnerabilities. You can enable it explicitly by passing the -Dappdynamics.agent.tls.allowedAlgorithms property to your startup script.
