PH42265: START OF CICS WITH OSGI JVM SERVER FAILED WITH MANY MESSAGES LIKE: INTERNAL: TRACE TOO LONG TO PRINT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The log of a CICS region with an OSGI JVM server was flooded
  with thousands of the following messages during startup:
  
  LE-Thread-0 DFHSJLOG Warning: logString() - INTERNAL: TRACE
  TOO LONG TO PRINT
  The problem was caused by a wrong profile for the JVM.
  Customer did a define with
  OSGI_BUNDLES=&OSGI_BUNDLES;,/xxx/yyy/zzz
  The trace (CICS system initialization parameter STNTRSJ=ALL and
  JVM system property -Dcom.ibm.cics.jvmserver.debug=true)
  showed a loop in replace_generic_symbols() and &OSGI_BUNDLES was
  replaced again and again.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS Users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Recursive variable within JVM Profile   *
  *                      causes infinite loop.                   *
  ****************************************************************
  A JVMSERVER is installed into CICS using a JVM Profile that
  contains a number of variables.  One of the variables is self
  referencing, for example
  
  OSGI_BUNDLES=&OSGI_BUNDLES;/directory/mybundle.jar
  
  As the profile is parsed this recursive reference causes CICS
  to loop attempting to resolve the variable.  This causes the
  following message to be output on the CICS log:
  
  2021/11/22 12:38:43.999316 --- SYSTEM W LE-Thread-0 DFHSJLOG
  @Warning: logString() - INTERNAL: TRACE TOO LONG TO PRINT = 8310
  

Problem conclusion

• JVMSERVER profile parsing code has been updated to correctly
  identify recursive variables and output an error message.
