Hi Matej Novotny,

thanks for the reaction. I missed the `decorate` call in the deploy()-method, thanks for pointing it out. I can confirm that my testcase succeeds after adding the `DecoratorWhichOnlyOverridesMethodWithDefaultImpl` to this call.

However, I am still struggling with a decorator which only started working after I moved default impls to the abstract class. I thought I had tackled the problem but it looks like it might be something else.

You wouldn't happen to have any pointers on where to set breakpoints to find out why weld decides to intercept some calls but not all, do you?
