Fixing an eclipse crach
Recently I wasn’t able to start up my Eclipse (vaugly remembering having an X-hangup – x-windows crach I mean). All I got was a small error dialog with a reference to eclipse log file containing huge traceback of java exceptions.. I didn’t have the time or energy to trace this so I swaped to jEdit for a while.
Sooner or later one has to deal with the problems. The later was today.. My method became deleting each plugin path under [workspace path]/.metadata/.plugins/
The solution was quite simple.. I removed the file .snap in the [workspace path]/.metadata/.plugins/org.eclipse.core.resources/ path and it started working again! 
I’m no expert in how Eclipse handles it’s workspace data, but apparently I lost associated projects.. ..but that’s that not so tuff to add again.
