  ****************************************************************
  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
