GitHub Plugin

Hello everyone

I am trying to set my GitHub credentials within the Github Plugin on Windows 7 (64-bit, Java 6) and on Ubuntu 12.04 (64-bit, Oracle JDK 6). On both OS the IntelliJ IDEA throws a ClassNotFoundException.

Google did not find any existing issues so I'd like to ask the community if you know that problem. Is Jetbrains aware of that issue?

Best regards
