Re: Can't compile in eclipe - unhandled event loop exception

This seems really odd - I know that we really only tested GPE against STS 2.5.0 (if you want GPE to work with Roo and Maven project in STS, you need to be using STS 2.5.0), but I still do not understand why you'd be running into problems against an Eclipse 3.5 version of an older incarnation of STS.

Did you have the Google Plugin for Eclipse installed previously? Was this an upgrade?
