           Summary: Properly parse StackMapTable attributes in Java 6
                    classfiles
           Product: BCEL
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Main
        AssignedTo: bcel-dev@jakarta.apache.org
        ReportedBy: mcmartin@gmail.com


Java 6 includes a "StackMapTable" type that is used for its new split
verification scheme.  This means many Code attributes will have StackMapTable
attributes attached.  This format is similar but not quite identical to the
already implemented StackMap.

I have developed a patch that adds the necessary functionality to the classfile
parser (mostly by copy-pasting code from StackMap and StackMapEntry), and will
attach it shortly

More than happy to apply this patch ...but could you also make sure there are
some test for it? Plus it currently breaks compilation for the tests.

correct patch

The previous patch is an earlier attempt that rewrote the StackMap parser
itself, and does not retain compatibility.  This is the correct patch. 
Apologies.

Simple patch to add StackMapTable parsing

This patch is largely directly derived from StackMap and StackMapEntry; it does
not properly update Javadocs yet because I am unsure if this is actually the
approach you want to take.  I can perform the documentation updates on request.
