PM77008: Rational Developer for System z (RDz) Outline View fails with Empty Stack Exception in PLI Outline Parser

Rational Developer for System z Fix Pack 1 (8.5.1.1) for 8.5.1

APAR status

• Closed as program error.

Error description

• Rational Developer for System z - RDz - v8.5
  
  The PLI Outline Parser causes an Empty Stack Exception and the
  Outline view displays nothing.
  
  When the following PLI code exists it causes a EMPTY Stack
  exception in the PLI Outline Parser:
     check_value: proc;
       dcl 1 test,
        7 a char(2),
        7 b char(2);
       if test.a = test.b then
        test1:
        do;
          display( 'test.a = test.b' );
        end test;
     end check_value;
  
  To avoid the problem if the 'end test;' is changed to end;
  then it works, or if the dcl is not a structure it works.
  
  This same problem does NOT happen on v8.0.3.3 client.
  
  The following exception occurs:
  java.util.EmptyStackException
