Since I am using lunareclipse-plugin + eclipse 3.2 for lua development, I sometimes face the problem (when my pc got switched off too early when trying to hibernate) that eclipse does nothing but crashing when I try to start it.

Log states something like that:

1
2
3
!ENTRY org.eclipse.core.resources 2 10035 2009-06-30 22:19:06.772
!MESSAGE The workspace exited with unsaved changes in the previous
session; refreshing workspace to recover changes.

... and crashs.

I managed to make it working again, by heading to the workspace directory.

workspace\.metadata\.plugins\org.eclipse.core.resources and removing the file .snap.
