Re: [aspectj-users] AspectJ syntax errors in AJHotDraw -v0.4

I'm afraid I'm not familar with the AJHotDraw codebase, does it just
need bringing 'up to date' (I remember hearing about it a few years
ago).  If you have a git repo or source zip, I might be able to find
the time to open it up and see what is wrong.
