Error description

• IBM Rational Developer for System z - RDz - v9.5.1
  IBM Developer for z Systems - IDz - v14
  
  The handling of adjuncts (comments, sequence numbers,
  resolved copy statements, resolved replace statements) in the
  incremental parse may cause this exception.
  
  When you save a file, the cobol editor will throw away
  everything and do a fresh, complete parse, but when you edit
  the file, the editor tries to save time by only re-parsing
  the part of the program where the edit takes place.
  
  Therefore, the editor keeps the portions of the parse
  structure and tries to adjust them as necessary.
  
  There are problems keeping track of adjuncts in the edit
  scenario.
  
  To recreate:
  
  Turn on Finest for the following settings in
  Windows > Preferences > Tracing:
  
  Select the following Tracer Names one a a time and right
  click on the Tracing Level to set to Finest:
  com.ibm.ftt.common.language.cobol
  com.ibm.ftt.common.language.manager
  com.ibm.systemz.cobol.editor.core
  com.ibm.systemz.common.editor
  
  The following exception can be found in the .trace file:
  com.ibm.systemz.common.jface.editor.parse.ReconcilingStrategy
  com.ibm.systemz.common.editor(FINE):
  parseAll()null
  
  java.lang.ArrayIndexOutOfBoundsException
  at java.util.ArrayList.elementData
  at java.util.ArrayList.get
  at com.ibm.systemz.cobol.editor.core.parser.
                       CobolPrsStream.getReplaceStrings
  

Local fix

Problem summary

• Editing a COBOL program  may cause an ArrayIndexOutOfBounds
  Exception when sequence numbers are present and certain optional
  paragraphs are present in the IDENTIIFICATION DIVISION.
  

Problem conclusion

• Modified incremental parser to properly handle comment and
  sequence number indices when optional paragraphs are present in
  the IDENTIFICATION DIVISION.
  
  The problem listed in this APAR has been resolved with
  IBM Rational Developer for z Systems V9.5.1.4 Fix Pack which
  is available from the Recommended Fixes support download page:
