What is the meaining of the following message appearing in the Log window?

Eric Rizzo

This message indicates a general internal error in VAJ. Sometimes it means that the user is trying to do someting that the IDE does not like, but often it is a sign of a corrupt workspace. In VAJ, the workspace can become corrupt for a variety of reasons, but luckily it is an easily recoverable situation.
If you get this message and you're not trying to do something out of the ordinary, the standard suggestion is to try replacing your workspace file with a fresh, clean one. For information on replacing your workspace file, see I have read about replacing the workspace file ide.icx with a "clean" or "fresh" one. How do I do that?
