     [ http://jira.jboss.com/jira/browse/JBDS-353?page=all ]

Viacheslav Kabanovich resolved JBDS-353.
----------------------------------------

    Resolution: Done

I could not reproduce the issue, but its cause is evident. Method getLocation() in IResource can return null, for instance, if resource was removed and ui thread requests it when processing previous events before the reference is removed from view.
