Nick Boldt commented on JBIDE-10134:
------------------------------------

Does this still happen w/ the latest JBT/JBDS from the Beta1 branch?

http://download.jboss.org/jbosstools/updates/nightly/core/3.3.indigo/
http://www.qa.jboss.com/binaries/RHDS/builds/staging/devstudio-5.0_stable_branch.updatesite/product/

Please document what you installed, then uninstalled, to cause this failure. Also, when attempting to reproduce, use a new (empty) workspace.
