  * PROBLEM DESCRIPTION: A memory leak occurs when processing    *
  *                      applications which contain security     *

  ****************************************************************
  A memory leak occurs when processing applications which
  contain security related annotations.
  The memory leak occurs when processing the annotations
  javax.annotation.security.DeclareRoles
  javax.annotation.security.RolesAllowed
  javax.annotation.security.DenyAll
  javax.annotation.security.PermitAll
  javax.annotation.security.RunAs
  These annotations can be used by web modules and by EJB
  modules.
  The memory leak can occur both when deploying applications and
  when starting applications.
  The problem does not occur for applications which contain the
  specified annotations but which are marked as metadata-
  complete.
  

Problem conclusion

• The memory leak occurred because of static reference to
  security metadata which was retained even after annotation
  processing completes.  The problem was fixed by a code update
  which removed the static references to security metadata.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 7.0.0.43.  Please refer to the Recommended Updates
  page for delivery information:
  http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
  
  This problem does not occur in IBM WebSphere Application
  Server v8.0, or in any subsequent fix pack or release.
