Re: [aspectj-dev] Need help interpreting ajc NullPointer dump

[Dean Wampler <dean@xxxxxxxxxxxxxxxxxxxxx>]

Thanks Andy.

Indeed, I'm using annotations in the source code and matching against 
them in pointcuts. I'm also compiling everything from source.

I actually eliminated the problem when I refactored my pointcuts (for 
other reasons...), but I'll try to reproduce a test case and enter a bug 
for it.
