[Soot-list] annotation bug ?

[Eric Bodden]

I had a further look at this. ASM has a specification here...
http://asm.objectweb.org/asm153/javadoc/user/org/objectweb/asm/attrs/RuntimeVisibleParameterAnnotations.html
... but I cannot really find anything wrong.

The relevant methods in question are these here:

https://svn.sable.mcgill.ca/wsvn/soot/jasmin/trunk/lib/jas/src/jas/Method.java?op=file
https://svn.sable.mcgill.ca/wsvn/soot/jasmin/trunk/lib/jas/src/jas/ParameterVisibilityAnnotationAttr.java?op=file

The only thing I found that might be wrong is that...
        if (list == null){
            out.writeShort(0);
        }
        else {
            out.writeShort(list.size());
            //System.out.println("num params: "+list.size());
        }
..in ParameterVisibilityAnnotationAttr.java may have to be replaced by...
        if (list == null){
            out.writeByte(0);
        }
        else {
            out.writeByte(list.size());
            //System.out.println("num params: "+list.size());
        }
... because according to the ASM docs num_parameters is a byte (u1)
value. This does not seem to fix the problem, though. Matteo would you
mind browsing through the Jasmin code a bit and see if you can see
something else that's not compliant with the specs? If you do find
something please let me know and I'll attempt a fix. The following
tool might also help to further track this down:
