PI91840: CICS: CICSTHREADFACTORY.C: ERROR _DFH_SJKIP UNDEFINED WHEN STARTING JVM SERVER

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When starting a Liberty JVM server in CICS, it receives the
  following message written to STDOUT:
  
     CICSThreadFactory.c: ERROR _DFH_SJKIP undefined
  
  This message is written when SJKIP has been scanned in but is
  NULL but the dump showed that _DFH_SJKIP was set correctly;
  
   _DFH_SJKIP=24907800
  
  Typically this error should not occur because one of the first
  things the IPT does it to set the _DFH_SJKIP environment
  variable.  This occurs way before we attempt to start the JVM.
  The variable should always be found and converted back to an
  address by the CICSThreadfactory code later.
  
  This turns out to be a timing and concurrency issue between two
  threads.

  * PROBLEM DESCRIPTION: Error message "CICSThreadFactory.c:     *
  *                      ERROR _DFH_SJKIP undefined" is          *

  ****************************************************************
  A Liberty JVM server is starting up in CICS. A pool of threads
  and their associated T8 TCBs will be created for Liberty to use.
  As the code to create these threads in CICSThreadFactory.c is
  not threadsafe, error message "CICSThreadFactory.c:
  ERROR _DFH_SJKIP undefined" is received in STDOUT.
  

Problem conclusion

• CICSThreadFactory.c has been updated to handle _DFH_SJKIP in a
  threadsafe way.  The error message now goes to STDERR instead of
  STDOUT.
