Title:
OpenJdk 7 and OpenJdk 8 miss-report the os.arch field and cause java
apps to crash.
Status in openjdk-7 package in Ubuntu:
Fix Released
Status in openjdk-8 package in Ubuntu:

Bug description:
Problem Description
=======================================
OpenJdk 7 and OpenJdk 8 miss report the os.arch field and cause java apps to crash.
When we run under OpenJDK on a ubuntu ppc64el system the os.arch
system properites gets reported as ppc64.
This causes multiple java libraries to load the wrong native
architecture modules as it thinks this is a big endian machine, rather
than a ppc64le machine.
---uname output---
Linux tulgpu002 3.16.0-30-generic #40-Ubuntu SMP Mon Jan 12 22:07:11 UTC 2015 ppc64le ppc64le ppc64le GNU/Linux
Machine Type = 8247-42L
Steps to Reproduce
===================================================
make sure an openjdk is installed.
sudo apt-get install openjdk-7-jdk
Create a very simple java properties dumper.
cat >sysprop.java <<EOF
class sysprop{
public static void main(String[] args){
System.getProperties().list(System.out);
}
}
EOF
and run it and look for the os.arch output.
javac sysprop.java
ralphbel@tulgpu002:~/java$ java sysprop | grep arch
os.arch=ppc64
sun.arch.data.model=64

Acutally this is ubuntu 14.10.
ralphbel@tulgpu002:~/java$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.10
Release: 14.10
Codename: utopic
I suspect this problem also exists on the ubuntu 14.04 releases
although we have not tried that yet...

This is an interesting comment in the openJDK bugs database:
****************************
https://bugs.openjdk.java.net/browse/JDK-8073139
****************************
apparently there was a decision to NOT give the architecture a unique
name, and that is inconstant with other JDK/JRE's, and it breaks a LOT
of code.
