[Soot-list] Error when retrieving the body of a method in abc

[Eric Bodden]

Hello.

This was explained more or less in this thread already:
http://www.sable.mcgill.ca/pipermail/soot-list/2006-February/000513.html

In a nutshell: At this stage you have to make sure manually, that Soot
loads the class to the right level. At the moment it seems to be at
"signature" level only, which does not expose any code information.
