see the Java_solaris bug #4139432, as well as #4141690 and #4141698 for examples of this problem.
The solaris native awt code for Frames and Dialogs intentionally sets up widget with wrong insets, then resizes multiple times as the
widget is reparented to the window managers shell. This causes what we call "the resize dance" where the window is visibly resized,
repositioned, and re-painted while comming up.
