        Description

        FULL PRODUCT VERSION :
        java version "1.7.0_09"
        Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
        Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode)

        ADDITIONAL OS VERSION INFORMATION :
        12.2.0 Darwin Kernel Version 12.2.0: Sat Aug 25 00:48:52 PDT 2012; root:xnu-2050.18.24~1/RELEASE_X86_64 x86_64

        A DESCRIPTION OF THE PROBLEM :
        If the size of a JFrame is within 10 x 10 pixels of the available screen bounds then setting the framestate to Frame.MAXIMIZED_BOTH actually MINIMIZES the JFrame.

        REGRESSION. Regression from Apple's Java 6uX

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        Run the attached code snippet and observe that the JFrame is minimized when the frame state is set to Frame.MAXIMIZED_BOTH.

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        JFrame stays at existing size
        ACTUAL -
        JFrame is minimized as much as the minimum layout size allows

        REPRODUCIBILITY :
        This bug can be reproduced always.
