Re: Two MethodVisitor with the same instances of Labels

In TreeAPI you can visit the instructions list only. Some thing like:
methodNode. instructions.accept(visitor).

The methodNode.accept(...) will reset the label if the methodNode was
already visited.

So, my approach is: first, visiting only the instructions list, collect the
information that you need. then use the secondVisitor exactly how you
doing. :)
