  ****************************************************************
  WebSphere Application Server attempts to delete application
  files when updating an application. If the files are locked
  the file deletion fails.
  There is a possibility that the file is locked due to a Java
  bug described at
  http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6213298
  To work around the problem, WebSphere Application Server
  requests a Java garbage collection which, if it occurs, will
  unlock the file.  However, there is no way to force a garbage
  collection and no reliable way to determine if a garbage
  collection has occurred.  For this reason, the application
  server will retry multiple times with a slight delay and a
  request for garbage collection each time.  When multiple files
  are locked, the delay can be considerable.
  

Problem conclusion

• The code has been modified to avoid retrying to delete files
  after the first unsuccessful file deletion.
  It will still make multiple attempts to delete the first
  locked file, but will only  attempt to delete the remaining
  files one time.
  
  The fix for this APAR is targeted for inclusion in fix pack
  8.5.5.18 and 9.0.5.4. For more information, see 'Recommended
