What is wrong with http://harmony.apache.org/ ?

It is a from scratch implementation of the JVM. And is backed by IBM AFAIK.

What's wrong is that Oracle won't (ever) allow Harmony to be called Java Compatible™, even though it is.

The same can be said of a fork. It will not be allowed to run the Java test suite (I forget the name) and certify itself Java.
