http://java.net/jira/browse/MACOSX_PORT-385 submitted 2011/09/09 by Yuri Nesterenko
There is an optional feature of the Frame setMaximizedBounds(Rectangle). It does override a system-provided rectangle for the Frame, when maximized. It is optional in a sense that a platform may not honor it at all or use only size and/or not location of the user-supplied Rectangle. For instance, Apple JDK 6 and MS Windows does use all of the Rectangle; Gnome totally ignores location; Xfce ignores everything.
As of now (September) Mac Port does ignore this hint. Perhaps we even should consider it a regression from jdk 6.
I'm attaching a trivial example file for convenience.
