Error description

  • The com.ibm.ws.webbeans.services.JCDIComponentImpl.earDrum
    IdentityHashMap<EARFile, EarData> is leaking EarFileImpl
    instances leading to leaks of EarFileImpl, WarFileImpl and
    EJBJarFileImpl objects across module updates.

    * USERS AFFECTED:  All users of IBM WebSphere Application      *

    *                      starting, stopping and updating         *
    *                      modules in applications.                *

    * RECOMMENDATION:                                              *
    ****************************************************************
    The com.ibm.ws.webbeans.services.JCDIComponentImpl.earDrum
    IdentityHashMap<EARFile, EarData> is leaking EarFileImpl
    instances leading to leaks of EarFileImpl, WarFileImpl and
    EJBJarFileImpl objects across module updates. This leak occurs
    when a module inside an ear is updated or restarted, not if the
    entire application is updated or restarted.
    

Problem conclusion

  • The CDI service class JCDIComponentImpl no longer caches
    reference to older EARFileImpl objects. The
    IdentityHashMap<EARFile, EarData> has been removed. The
    application logical name is now derived through the
    application and module metadata that is stashed in a
    ThreadLocal by WebSphere Application Server runtime.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.0.0.2.  Please refer to the Recommended Updates
