Hi, I'm trying to use wicket 7.2.0 and saw in the migration guide that other libraries also changed to the latest stable version. So I also tried this, and the following are used by me now: - Spring Framework 4.2.5 - ASM 5.1 - CGLIB 3.2.1
I get the following stacktrace, on which I'm really lost, and could not find any answer on the internet on.. Thanks for any help.
