Re: gnu.bytecode: Method without Code Attribute

[Chris Wolfe <cwolfe at globetrotter dot qc dot ca>]

Looks like it was a bug, unless I'm misreading the source,
constant pool entries were never assigned for methods with null
code blocks. The following modification (sorry, not quite diff
format) appears to solve the problem.

gnu/bytecode/ClassType.java, line 565:

   for (Method method = methods; method != null; method =
method.next) {
     CodeAttr code = method.code;
     if (code == null)
++     {
++       method.assign_constants ();
         continue;
++     }
     for (;;)
       {
         CodeFragment frag = code.fragments;
         if (frag == null)
           break;
         code.fragments = frag.next;
         frag.emit(code);
       }
     method.assign_constants ();
     method.code.finalize_labels ();
   }


Cheers,
Chris
