outch, I whouldn't recommend that to anyone!

- you throw away maybe lots of local workspace data and configuration
- this isn't a workaround, it just hides the problem until your workspace
  configuration/data is again in shape to trigger the problem

In the current situation, there are two known resolutions or workarounds:
- use a Java-5 JRE to run ECLIPSE (note: you can still use a JDK-6 inside for your programs)
- use the newest updates for sun java-6 (> update 11)
