Error description

• Rational Developer for System z - RDz
  COBOL parser may throw a Java Array IndexOutOfBounds Exception
  for programs that use COPY... REPLACING statements.
  
  This problem may occur in either the COBOL editor or the
  System z LPEX editor for a COBOL program.
  
  You may see a popup dialog when you attempt to save a
  program stating:
  An error dialog opens:
  Save Failed  Index: 5870, Size: 5870
  
  You may see a similar condition when you add the OCCURS
  multiple times to a copybook while in one of the editors.
  
  In this case if you add the OCCURS 300 times then you may
  see that all references to fields in copybook TEST03 get
  "UNABLE TO RESOLVE REFERENCE".  Below is the code in the
  program:
      COPY TEST03.
  
  In the copybook it has:
         copy TEST03 replacing == 03 pCapability ==
                by == 03 pCapability OCCURS 300 TIMES ==.
  
  
  Below is an example of a stack trace found in one case:
