If you have not created any projects delete the workspace directory and try running eclipse again. This usually works. If you have any projects inside of the the workspace directory, copy them outside of the eclipse folder, and delete the workspace directory. Once eclipse has started successfully, exit it and copy the project contents into the newly created workspace directory.

Hope this helps.
