I have a source file which should compile (as far as I think), but instead I get a NPE from the JDT compiler, which looks like this:

The .log file also has another variation of the same stacktrace:

Unfortunately I am not allowed to post the original source. I can only hope that you see it when you look at the methods in the stacktrace. Or maybe you know this one already. :-)

Best wishes
