[Soot-list] How can I change method's parameters types

[Eric Bodden]

Well, apparently whatever list throws this exception is being modified
while somebody (presumably your manually created thread) iterates over
it. Are you instantiating multiple such threads or just one? It's hard
to say. I guess you need to use a debugger there...
