Using the recently upgraded linux kernel machine, north-star,
Linux version 2.4.20 (root@jtg-it4) (gcc version 2.96 20000731 (Red Hat Linux 7.2 2.96-112.7.2)) #4 SMP Tue Jun 3 13:10:01 PDT 2003, I got HotSpot VM crash during the Java2D demo runtime.

The VM crash also happens in original 2.4.18 kernel.

STEP TO REPRODUCE:
1. Upgrade the linux64 from 2.4.18 kernel to 2.4.20 kernel.
2. Install JDK1.5.0 b16 bundle.
3. Launch Java2D with one of following 3 options:
a) j2sdk1.5.0/bin/java -jar -server j2sdk1.5.0/demo/jfc/Java2D/*.jar
b) j2sdk1.5.0/bin/java -jar -server -Xint j2sdk1.5.0/demo/jfc/Java2D/*.jar
c) j2sdk1.5.0/bin/java -jar -server -Xcomp j2sdk1.5.0/demo/jfc/Java2D/*.jar

4. Click on "Options" -> "Run Window"

5. When the Run Window pops up, click on Run button.

6. After a few runs, the VM crashes and the following hs_err_pid~.log are created respectively.

Results:
#
# An unexpected error has been detected by HotSpot Virtual Machine:

The VM crash also happens with the original 2.4.18 kernel:
