I have an @Aspect with a number of simple @Pointcuts, which are then combined in another @Pointcut which is combined with some others in an @Around advice.
When I changed the pointcut in the @Around (from something legal to something else legal), an error dialog appeared containing the following exception:

java.lang.NullPointerException

Looks like the getResolvedSignature() call within the Shadow.getGenericArgTypes() method returned null.   There are some convoluted routes through that method which could lead to a null but without more to go on, it'll be tricky to investigate further.  Let me know if you see it again, I'll bump this bug down to a lower priority for now.
