PH45006: During server shutdown OSGi applications may log null pointer exceptions (FFDCs).

APAR status

• Closed as program error.

Error description

• If OSGi applications are installed they may log
  NullPointerExceptions in FFDCs during server shutdown. This
  can happen if access to the services which were removed as
  part of shutdown are attempted.

  ****************************************************************
  During server shutdown an installed OSGi application might log
  FFDC messages containing NullPointerException. This can happen
  if a server shutdown is requested while applications are still
  starting and the use of a service removed by the shutdown is
  attempted.
  

Problem conclusion

• Prior to the APAR the null pointer exceptions were more likely
  to occur because  at shutdown references to some services were
  removed more aggressively than necessary. The code has been
  changed so that the service references are not removed as early
  in the shutdown process.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 22.0.0.4.  Please refer to the Recommended Updates page for
