APAR status

• Closed as program error.

Error description

• During annotation processing there are excessive amount of
  addAnnotationInfo Concurrent Modification warning messages that
  are due to a reentrant callback.  There most likely is no REAL
  concurrent modification and these warning messages are
  misleading and should be done ONLY if there is a real
  possibility of a concurrent modification exception.

  * PROBLEM DESCRIPTION: Excessive warning log messages          *
  *                      indicating a Concurrent Modification    *
  *                      in addAnnotationInfo.                   *

  ****************************************************************
  The code did not take into account some reentrant cases where
  we are looking to add annotated classes that have previously
  been added to our list.
  

Problem conclusion

• The logic that looked for this Concurrent Modification warning
  was moved to the areas of code that can actually cause a
  ConcurrentModifcationException to be thrown.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 7.0.0.15.  Please refer to the Recommended Updates
