Hi Dean,

the arm32 byte interpreter and jit is developed here http://openjdk.java.net/projects/aarch32-port/ and
fornatly orcale has openend up there closes source arm32 jit too. With thoughts to include it for
java/openjdk 9. So to get fast arm32 java no you need to checkout the mercurial repository from there and
modify the existing recipes.

Bye Henning
