Hi all,
After upgrading to Galileo, when I try to open an object's declaration I (sometimes) get the following pop up error:

Please file a bug report against AJDT.

The project uses AspectJ and Maven.
Here are the plugins versions:
Maven integration for eclipse: 0.9.8.200905041414
AspectJ Development tools: 2.0.0.e35x-20090624-1600
AspectJ version: 1.6.5.20090618034232
I'm running ubuntu 9.04
There are other errors on the log that may be related (different message, similar stacktrace), if anyone is interested I will post them.

The error seems to be associated with the origin point (if class A is 'cursed' and Class B isn't, then I cannot open Class C's declaration starting from A, but I can open it from B)
I have searched on google but there doesn't seem to be anything useful.
Any help would be greatly appreciated.
Regards,
Santi
