--- Comment #10 from Roland Grunberg rgrunber@redhat.com --- (In reply to Hedayat Vatankhah from comment #9)
What I can add is this: the day I reported the bug, when I removed my workbench.xmi completely, I could run Eclipse once. But the next try (after closing Eclipse without ANY customization, so the default setup. The only thing I might have done was to change the perspective from default to C++) it didn't run.
Is there any possibility that you had another Eclipse instance (or Equinox runtime) that was running at the same time as your main Eclipse instance ?
The reason my method of reproduction worked was because the application I was debugging was an Equinox instance sharing the exact same configuration/install area as my main one. This likely caused some race conditions leading to the strange behaviour and re-wiring.
On the other hand your case doesn't mention any of these so there may well be some other way to produce the same errors you're seeing.
