Another obscure and unhelpful error message that now pops up about once every five minutes while I'm working in Eclipse. Upgraded to Eclipse 3.5 a day before the official release (thanks to my Friends of Eclipse membership), but to no avail. Evidently my workspace is pooched somehow.
Why can't more error messages tell you *HOW TO SOLVE THE PROBLEM*, rather than just reporting that something went wrong? Surely as software devs we should be able to do better... if for no better reason that to avoid having to listen to end users like myself complain? :P
