Thanks Thomas. That worked as you suggested! I was almost sure it was a
compiler / dev library issue since it worked in dev mode.
Just curious, what could be the reason that GWT would ignore serialization
of the runtimeexception type from the source folders?
Now, the custom AccessDeniedException is purely cosmetic on the service
interface as it is always thrown outside the method by Spring Security.
Thanks again for your help!
