    ****************************************************************
    During server startup, while starting applications, a
    ConcurrentModificationException modification exception can occur
    from
    AnnotationScannerImpl while processing application annotations.
    
    The exception is logged to trace logs, however, application star
    proceeds.
    
    As a consequence of the exception, application metadata may be
    incomplete.
    
    For example:

Problem conclusion

  • The problem occurs because of unsynchronized access to shared
    annotation processing data objects between distinct module and
    application startups.
    
    The problem was fixed by a code update.  Synchronization was
    added to shared data objects which are used during annotation
    processing.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.11.  Please refer to the Recommended Updates
