System tested:
bunt
SuSE SLES-8 (AMD64)
VERSION = 8.1
Linux bunt 2.4.19-SMP #1 SMP Mon Mar 31 23:48:08 UTC 2003 x86_64 unknown

STEP TO REPRODUCE:
------------------
1. install SWAT b32 bundle rpm.bin bundle on AMD64-SLES machine
2. invoke the Java2D demo
3. open the "run windows" pop-up window and let it run for 10 times.
