Eclipse: Open Type/Resource working again under Linux!

Some weeks ago the extremely useful features of Eclipse Open Type and Open Resource stopped working, throwing an uninformative  Error instead, no matter which version or JRE vendor. I was desperate. Until finally I found a bug regarding this issue which pointed me to the solution - switching off Gnome's assistive technologies (System - Preferences - Assistive Technologies - uncheck Enable assistive technologies under my Ubuntu 9.04 Jaunty). Thanks, allmighty powers of digitalized universe!
