sample project with the NPE

Comment 2 Sian January 2006-03-24 05:32:21 EST

Looks like an AspectJ bug.

Comment 3 Andrew Clement 2006-03-27 16:40:59 EST

project is too complex for me to use - lots of dependencies. but I've tracked the line with the NPE in and put in a reasonable change so it can no longer happen. so i believe this is fixed.

I got almost the same stack trace with a project based on Ramnivas Laddad's Authorization Project (AspectJ project) from chapter 10 of his book:

(In reply to comment #4)
I'd like to add that this was also due to an unimported class in an about advice.

Comment 6 Andrew Clement 2006-04-04 14:02:33 EDT

fix for this should be in 1.5.1 and its related AJDT (due in a day or so)

Comment 7 Andrew Clement 2006-04-12 04:04:31 EDT

npe can't happen any more (I bravely claim) - please reopen if you any of you see something similar on the most up to date AJ/AJDT.
