Error description

  • When starting a server some applications may fail to start.
    If the application is an enterprise bundle archive application
    the following error message can appear in the logs:
    
    com.ibm.ws.classloading.ClassLoadingServiceException:
    CWWKL0003E: The system could not create a class loader for the
    application [ThreadContextClassLoader] at version [null].
    at
    com.ibm.ws.classloading.internal.GatewayBundleFactory.createGate
    wayBundleClassLoader(GatewayBundleFactory.java:63)
    
    This problem may also be seen when there are multiple
    applications that are being installed via the dropins
    directory and one of the applications will start but the other
    applications installed via dropins do not.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty Profile, primarily those     *
    *                  using enterprise bundle archives (EBAs).    *
    ****************************************************************
    * PROBLEM DESCRIPTION: After starting the Liberty server an    *
    *                      application does not start.             *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    There are 3 main scenarios covered by this APAR, those being:
    1.  After starting the Liberty server an application does not
    start. In the console the following message appears after 30
    seconds. CWWKZ0022W: Application * not started in 30.009
    seconds.
    This is because as an application is initialized it receives a
    classloader and the classloading service may not have been
    initialized at the moment the application starts.
    2.  If you have an EBA application running under a Liberty
    server it is possible that the application may fail to start.
    The messages.log file includes a message like the following:
    [5/17/12 15:48:52:570 BST] 0000002a
    org.apache.aries.application.resolver.obr.OBRAriesResolver   E
    An internal error occurred. When provisioning the EBA archive
    MySimpleOSGiApp, cannot read the repository
    file:/test/wlp/usr/servers/app_dir/workarea/platform/resources.x
    ml.
    3.  If the liberty server has multiple applications in the
    dropins folder its possible than one or more applications will
    not start.
    This should only occur when multiple applications are in the
    dropins folder. The first application will start up but it is
    possible that other applications could hit a faulty timing
    window and not start up. There will be no error messages or
    any information in the log to say that the application tried to
    start or that there was a problem.
    The problem occurs at server startup time, the first
    application to start does some server initialization and if
    the second application tries to start before this
    initialization completes then the server will not continue
    trying to start the application.
