    ****************************************************************
    During CDI bootstrap, the Thread Context Class Loader (TCCL)
    should be set to the classloader of the module that is being
    bootstrapped. This was not occurring leading to problems
    attempting to use the TCCL in a CDI extension and compatibility
    issues with Apache DeltaSpike.
    

Problem conclusion

  • New code was added to set the Thread Context ClassLoader.
    Because of technical limitations this code only sets a TCCL when
    there is only one module in the application. E.G. an EAR file
    with one only WAR inside it.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 9.0.0.5.  Please refer to the Recommended Updates
