Error description

• When running Java workload using Link to Liberty in CICS with

  .
   DFHSJ0002 applid A severe error (code X'0B07') has occurred in
   module DFHSJJS
  .
  But if Omegamon for JVM is removed, the problem does not occur.
  The 0B07 error code corresponds to the following exception
  trace entry:
  .
   SJ 0B07 SJJS  *EXC* - INTERNAL_ERROR -
                  FUNCTION(ASSOCIATE_TRANSACTION)

  ****************************************************************
  CICS is running a Liberty server, configured to use the
  cicsts:link-1.0 feature to allow program LINK requests into
  the Liberty JVM server.
  A LINK request to the Liberty JVM server fails, and DFHDSAC
  issues a trace entry:
  DSAC EXIT ASSOCIATE/EXCEPTION   FUNCTION_ALREADY_INVOKED
  .
  This results in msgDFHSJ0002:
  DFHSJ0002 A severe error (code X'0B07') has occurred in
            module DFHSJJS
  .
  This occurs because a separate TCB has already processed the
  same request (matching DSAC_ASSOCIATION_TOKEN token). This is
  made possible by reuse of the SJLLB before it can be removed
  from the request chain.
  .
  It is likely that prior to this time, another LINK request
  could not be initiated within the WLP_LINK_TIMEOUT time, and
  resulted in an exception from DFHSJJS on a T8 TCB trying
  to process the request:
  ASSOCIATE_TRANSACTION/EXCEPTION LINK_REQUEST_TIMEOUT
  .
  CICS issues msgDFHSJ1006:
  DFHSJ1006 An attempt to attach to JVMSERVER DFHWLP has
  failed because the Liberty link request has timed out.
  .

Problem conclusion

• DFHSJTH and DFHSJWLW have been updated to correct the
  management of the SJLLB request block.
