http://java.net/jira/browse/MACOSX_PORT-651 submitted 2011/11/03 by Yuri Nesterenko
Run the attached test adapted from a real one. There are three Frames and a Dialog. First, just look how robot clicks here and there. For me, both F2 and F3 frames consistently overlap the (modal) Dialog, so that's a bug and broken behavior, right? Now, when robot finished, try to click by hand on decorations and visible space in the frames: you will never get the same results – everything will works as designed.
It's bizarre. What is broken here?
