  The Controller Region was processing an ACRW for a Servant
  Region terminated event.  This processing involves notifying a
  number components that a particular Server Region has
  terminated so that the proper recovery and failover can occur.
  The Controller Region code driving the notification calls
  encountered an uncaught Java Exception between driving the
  cleanup code related to com.ibm.ws390.orb.JVMListenerNotifier
  and the clean code related to the com.ibm/ws390.recoverylog
  (bbogfm.cpp).
  A Java java.lang.NoClassDefFoundError exception was returned
  to the native code which drives the recovery routines for
  the JVMListenerNotifier cleanup.  There was no native check
  made for this uncaught Exception:
  java.lang.NoClassDefFoundError: com.ibm.ws.session.ws390.

  Later in the native code when it drove recovery related to
  the recoverylog, the NCDF Exception was detected from
  native module bbogfm and this resulted in the Exception
  being written to stderr via a call to the JNI routine
  ExceptionDescribe(), followed by an Assert which brought
  the Controller Region down.

Problem conclusion

• Code has been modified in module bboojsjn.cpp to check for any
  uncaught Exception when returning to the native after driving
  the java cleanup routines registered with the
  com.ibm.ws390.orb.JVMListenerNotifier.
  
  
  The fix for this APAR is targeted for inclusion in fix packs
  8.5.5.22 and 9.0.5.13. For more information, see 'Recommended
