I am using eclipse 2.1 with AJDT 1.4 / AspectJ 1.1.1. Editing and saving an 
aspect file (*.aj) that is not on the source path defined in eclipse sometimes 
gives the following exception (note: the aspect is by intention not a part of 
the source path because I do not want it to compile - but I do want to be able 
to edit it):
