Error message when select to install VJET from JBoss Central Software/Update tab:
"The following connectors are not available: Eclipse VJET Proceed with the installation anyways?"

Followed by:
"Problems occurred while performing installation: The following connectors are not available: Eclipse VJET (id=org.eclipse.vjet.js.ide.feature.group, site=http://www.qa.jboss.com/binaries/RHDS/discovery/development/8.0.0.Beta1a/)
