Seeing Unsupported major.minor version 52.0 on some plugins

If you have multiple Java versions installed, you should make sure that v1.6 is not being used.

On OS X machines, you can remove the JDK from being noticed. You can move it the temporary directory in case other issues are created by this change.

sudo mv /System/Library/Java/JavaVirtualMachines/1.6.0.jdk /tmp
