OK, i changed it (and everything which depends on it)

And it works!
Here is the output of my compiled example:

before the block

        before - TESTING - block(ClassNotFoundException aspectjtest.Test.(Test))
1. stmt in block
2. stmt in block
        after - TESTING - block(ClassNotFoundException aspectjtest.Test.(Test))

after the block

Now I can go on the the next thing. Perhaps you can give me a hint here, too.
I want to add arguments to the block so that i can capture these
arguments in my joinpoint.
Analogue to call/execution pointcut i want to use the arguments of the
block in the advice.

How can I do this?
I have seen that my ShadowMatch has the method getArgsContextValues().
But different from the MethodCallShadowMatch I have no invoke
statement, where i can get the args from. I have the info about the
args in my frontend and can pass them into the ShadowMatch in a Tag
(similar i do it with the start and end of block) but how do i create
the List of Immediate?

Thanks for your help.
