Deepak are you testing on Fedora v?

I have now tested the testcase on several machines:

### I can reproduce this bug using:
x86_64 Ubuntu Lucid 10.04
xranby at hp:~$ ./icedtea6-jamvm/openjdk.build/bin/java -version
java version "1.6.0_22"
IcedTea6 Runtime Environment (1.11pre+r1951b44ffa89) (Ubuntu build 
1.6.0_22-b22)
JamVM (build 1.6.0-devel, inline-threaded interpreter)

x86_64 Ubuntu Lucid 10.04
xranby at hp:~$ java -version
java version "1.6.0_20"
OpenJDK Runtime Environment (IcedTea6 1.9.2) (6b20-1.9.2-0ubuntu1~10.04.1)
OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode)

armv7 Ubuntu Maverick 10.10 running on armv7l hardware
maverick at babbage:/wd$ java -version
java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8) (6b18-1.8-2ubuntu2)
OpenJDK Zero VM (build 14.0-b16, mixed mode)



### I fail to reproduce this bug using:
armv5 Debian Squeeze running on armv7l hardware
xranby at babbage:~$ java -version
java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8.3) (6b18-1.8.3-2+squeeze1)
JamVM (build 1.6.0-devel, inline-threaded interpreter with stack-caching)

armv5 Debian Squeeze running on armv7l hardware
java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8.3) (6b18-1.8.3-2+squeeze1)
OpenJDK Zero VM (build 14.0-b16, mixed mode)



So from my experimentation and results obtained, it seems like this bug 
only triggers on Ubuntu systems. odd.

Can other people verify these findings?
Doko do you have any idea why this might be?
