Just a quick update to let you know that IcedTea 2.6 release should happen in a month or so according to its maintainer.

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:
  Incomplete
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.
