Patch Set 6:

Issue#1: I see no buttons in the dialog. Could it bee that it starts out taller than my screen (lots of build tags). When I resize the window there are still no buttons.

Issue#2: Clicking on an un-annotated tag gives an error
java.lang.IllegalArgumentException: Argument cannot be null
