--- Comment #14 from Mat Booth mat.booth@redhat.com --- I added a new build to the update, I would appreciate you trying with Eclipse version:
eclipse-4.6.0-0.6.git201605092000
When it arrives in updates-testing to see if that fixes the problem. (This also has other late-arriving important fixes, such as unbreaking the Help system.)
