Use demo EclipseConTest provided by your company. 1) Download Eclipse Ganymede for J2EE development 2) Start Jubula 3) Go to test properties and add new AUT configuration to GEF 4) Point to Ganymede 5) Start AUT via Jubula 6) Manually create new Java project 7) Manually add new class. Popup NoClassDefFoundError message occurs 8) Open log file and you can see message: Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".

You can create test which adds new class to the Java project but it is easy to reproduce error when you do it manually.
Was GEF installed with the Ganymede Eclipse? If not, this would explain the error.
OK. Forget about EclipseConTest and GEF. Use Eclipse Ganymede as your AUT. Add RCP plugin into plugins directory. Use the same steps: 5) Start AUT via Jubula 6) Manually create new Java project. Popup NoClassDefFoundError message occurs 7) Manually add new class. Popup NoClassDefFoundError message occurs 8) Open log file and you can see message: bla-bla-bla This error occurs each time when Jubula runs tests.
BTW I am using JEE version of Eclipse Ganymede (eclipse-jee-ganymede-SR2-win32) There is another point: you can start Eclipse manually and observe the same error.
This problem has also been noted in the GUIdancer Bugzilla: http://bugzilla.bredex.de/52
Vladimir, another customer who was having this problem found that after a resetup (uninstall and reinstall of Eclipse plugins), the problem no longer occurred. Are you still able to reproduce the problem after reinstalling plugins? If so, please let us know which GEF version plugins you are using.
Missed the cutoff for Indigo SR1. Re-scheduling to Indigo SR2.
As there has been no further input from the reporter, I am closing this bug as works for me.
