We found running jruby on the openJDK on ppc64 architecture throws an uncaught exception.

we obtained a the 1.7.20 snapshot from:

http://ci.jruby.org/snapshots/jruby-1_7/jruby-dist-1.7.20-SNAPSHOT-bin.tar.gz

and we constructed a very simple jruby script:

cat testdev.rb

require 'fileutils'

stat = File::Stat.new("./testdev.rb")
inode = [stat.ino.to_s, stat.dev_major, stat.dev_minor]

and then ran the following script:

jruby-1.7.20-SNAPSHOT/bin/jruby testdev.rb

and it produced the following output:

Mar 19, 2015 11:11:29 AM jnr.ffi.provider.jffi.NativeRuntime buildNativeTypeAliases
SEVERE: failed to load type aliases: java.lang.ClassNotFoundException: jnr/ffi/provider/jffi/platform/ppc64/linux/TypeAliases
NotImplementedError: stat.st_dev unsupported or native support failed to load
  dev_major at org/jruby/RubyFileStat.java:201
     (root) at testdev.rb:4

the java version is:

 java -version
openjdk version "1.8.0_31"
OpenJDK Runtime Environment (build 1.8.0_31-b13)
OpenJDK 64-Bit Server VM (build 25.31-b07, mixed mode)
