After having Eclipse installed and working fine for over a year, I opened up Eclipse Juno today and got a error message on opening the workspace. I am using Windows 8 64-bit, Java 64-bit, and Eclipse 64-bit. I have since tried re-installing Java and Eclipse without any effect. If anyone can help me get Eclipse working it would be much appreciated. The error log is as follows:

I think your answer is here:
$ mv <workspace>/.metadata/.plugins/org.eclipse.core.resources/.snap ~/temp/
or
$ rm <workspace>/.metadata/.plugins/org.eclipse.core.resources/.snap
Start Eclipse with Clean parameter.
eclipse.exe -clean
Thanks to Kninnug I have figured out that the issue is in my workspace not eclipse itself. I ended up just importing everything in to the new workspace. thank you everyone for your help though.
I am having the same problem with Eclipse Juno, which I use for Android development.
As a workaround for Windows, I launch it from the console like this:
C:\path\to\eclipse\eclipse -clean
or
DELETE: /[PATH TO WORKSPACE]/.metadata/.plugins/org.eclipse.core.resources
if none of the above works, have a read at this http://www.metod.si/job-found-still-running-after-platform-shutdown-eclipse/
problem is with workspace/project you are working on and not with eclipse. One solution would be if you are using maven is to clean and install.
