I have installed plug ins using plug in manager and all installed well. However when attempting to define servers i ereceive the following error

Plug-in org.jboss.ide.eclipse.deployer.ui was unable to load class org.jboss.ide.eclipse.deployer.ui.preferences.MainPreferencePage

Jira has an entry marked as resolved however I found nothing to show that it had in fact been resolved and am just wondering if I am missing something here.

No spaces in any directory name....
