OS: Windows XP SP2 Japanese + IE6
JRE: 1.5.0_16 (See comments)

If display change event continually happens when applet is running on IE, java heap will
be consumed gradually. And finally OutOfMemoryError appears.
This issue would be reproduced by changing screen color within "Display Properties"
of Windows.

Here's trace log when the issue happen.
