ok, had some time today to have a look again...
The getNext() is now done in the AbstractInterceptor.Invoke()...
so I just deleted all the lines in the LifecycleInterceptor.
Some strange things happen now and then wenn in the LifeCycle the invoke() is called
with type "invoke"... debug showed that "invoke, getLanguage" is called on the
MBeanAttributeInterceptor, which then throws an Exception because it does not
understand the command.
I just catched this exception and returned null in LifeCycle.invoke. It should not be
done this way, but now nukes deploys, at least...
Next problem ist a nullpointer:
15:02:19,484 ERROR [Engine] StandardWrapperValve[NukeServlet]: Servlet.service()
