Hello Canonical,

This same issue has also been reported on 15.04 by a different
originator in a different LTC bug. In addition, the originator of this
bug also states that the same fix is needed in 14.04. Can we please get
tracks opened for both these releases in bug 1438575 to deliver the
fixes there as well?

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:
  New

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.
