Eclipse LUNA hangs

Recently even eclipse LUNA version, hang occurs when launching it.

At the message "Android SDK Content Loader 0%". Very annoying and hope it will be fixed soon.

Following is work around with the problem.

This is the solution I found which works correctly:

1. Make sure that eclipse is not active. If it is active kill eclipse from the processes tab of the task manager
2. Open %USERPROFILE%/ (You can locate this folder from desktop)
3. Go to .android folder (This may be a hidden folder)
4. Delete the folder "cache" which is located inside .android folder
5. Delete the file ddms.cfg which is located inside .android folder
6. Start eclipse

and / or

Delete your debug.keystore:

Windows : %USERPROFILE%/.android

Linux or Mac : ~/.android/debug.keystore

and / or

cd workspace/.metadata/.plugins/org.eclipse.core.resources/.projects
$ rm -rf *

This one could be devastating, because it nullify all project in your package explorer.

That doesn't mean all the sources are deleted along, you need to re-create those project entries. 

I tried to look for a specific project in project list and could find one that cause the problem.
After deleting it, eclipse launched as usual.
