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:

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.
