robovm plugin won't work

Question

I'm trying to use robovm on Eclipse. I have installed the robovm plugin.

But when I create a RoboVM eclipse project, Eclipse gives me an exception:

The selected wizard could not be started.
Plug-in org.robovm.eclipse.ui was unable to load class org.robovm.eclipse.internal.NewCocoaTouchProjectWizard.
An error occurred while automatically activating bundle org.robovm.eclipse.ui (244).

I get a similar message when I try to go to "Settings" > "RoboVM":

Unable to create the selected preference page.
An error occurred while automatically activating bundle org.robovm.eclipse.ui (244).

Can anyone can help me?

For future readers, Here is the right answer:

But i've found and solved the Problem today. I had installed Java 6 AND 7. eclipse had use Java 6.

For other peoples there have the same Problem: Go to the Settings App > Java and go to the Java-Tab. Here are all installed Java versions listed. Change the priority for the version otherwise deinstall or disable older Versions.
