Bug 22380 "No Source" class file editor does not fetch keyboard focus
Build N20020813 Test Case: 1. From the package explorer open a class from a JAR without attached source 2. Activate the editor 3. Select something in another view (note: selection is blue) 4. Activate the class file editor by clicking on the tab ==> selection in other view remains blue but should be gray. Suggest to set the keyboard focus to the "Attach Source..." button
