I just experienced what probably many devs experience with Eclipse occasionally: It hangs on startup.
Looks like there is a pretty easy solution to delete a .snap file which helped me too:
- cd to <workspace>/.metadata/.plugins/org.eclipse.core.resources
- remove the file .snap

I am reposting it so I can find it easier in future
