Re: [aspectj-users] strange aspectj error
The tool versions could be an issue. Also, are the compiler flags for Java 5 vs. earlier versions consistent?
I'm not sure what's happening here, but I've occasionally solved similar problems with a clean rebuild, even just an hour ago! In this case, I think I was trying to use class files built with an older eclipse/ajdt combination.

My co-worker gets the stacktrace below when she tries to compile and

out of sync in her build environment, ie a old aspectj compiler or
something like that.  Any other ideas?
