This similar error has been popping up recently. My first question for you is to check your Java installation. It looks like you're running a 32-bit build of Java. Since you're running Win7 x64, you also should have Java x64 installed. You can verify this through the Java control panel and opening the "About" window. If it's not the 64-bit version, uninstall and make sure you get the correct install from this page:

This has been popping up recently and I've found some possible signs from other sites that it could be a driver issue that hasn't been fixed. You should still check your drivers and make sure they are up to date.
