PH33150: LOGGED MSG JAVA.LANG.STACKOVERFLOWERROR AFTER RUNNING AMS-COMPILER

APAR status

• Closed as program error.

Error description

• ADDI Batch Server's server.log file contains messages like the
  following:
  
  [ams-compiler] (cl.compiler.AmsCompiler:216) - Ams compiler
  finished.
  
  
  then:
  
   [ams-compiler] (thread.pooling.ThreadPooling:127) -
  uncaughtException on threadThread[ams-compiler,5,main]
  java.lang.StackOverflowError
   at
  org.antlr.v4.runtime.atn.ParserATNSimulator.closureCheckingStopS
  tate(ParserATNSimulator.java:1513)
  etc.
  
  and shortly thereafter is a message saying:
  
  finished task IDCAMS postprocessing with status Finished failed
  

Local fix

• none known
  

Problem summary

• A java.lang.StackOverflowError may occur while running the
  IDCAMS postprocessing task started by the Batch Server if a
  large IDCAMS step exists in the JCL file.  This is caused by
  the Java Virtual Machine (JVM) running out of stack memory
  during the processing of this file.
  

Problem conclusion

• Application Discovery code was changed to increase the maximum
  stack memory that the JVM is allowed to use. Also, code was
  changed so that if the error occurs again, it no longer stops
  the process, but skips the erroneous step in the JCL file and
  shows the error in the log.
  

Temporary fix
