        Description

        FULL PRODUCT VERSION :
        java version "1.5.0"
        Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64)
        Java HotSpot(TM) Client VM (build 1.5.0-b64, mixed mode, sharing)

        Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05)
        Java HotSpot(TM) Client VM (build 1.5.0_04-b05, mixed mode, sharing)

        ADDITIONAL OS VERSION INFORMATION :
        Microsoft Windows XP [Version 5.1.2600]

        EXTRA RELEVANT SYSTEM CONFIGURATION :
        HyperThreaded Intel Processor, 2 GB of system memory

        A DESCRIPTION OF THE PROBLEM :
        Swing fails to paint _ALL_ of the text on any GUI if it is started with a large heap size.

        For example, on my pc - '-Xmx1050M' works ok.
        However, the same application launched with '-Xmx1100M' fails.



        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        Run my provided class (without setting any heap size parameters)

        (alternatively - use any java swing application)



        Now run the class again with your heap size set very high - for example - '-Xmx1100M'

        Note that all text in the GUI fails to paint.

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        The GUI should behave the same no matter what the max heap size is set to.
        ACTUAL -
        No text appears in any Swing component.

        REPRODUCIBILITY :
        This bug can be reproduced always.
