My IDE crashes when loading a Drools project, with a OutOfMemoryError: PermGen space.

I have increased the perm gen size up to the limit my machine could handle (2G - screenshot attached) and tried both eclipse indigo with jboss tools and jboss developer studio, windows and linux, same error.

The project has 5956 rules in 882 .drl files

Is this a known issue? Should i add it to the issue tracker?
