Interesting, once I got it compiled (using Java 7) I could then run the
tests fine using Java 6 or 7.

Compile works, but tests seem to hang after:

changes in question (I hope, first time using git archive command). Can others using
alternative JDKs and other OS architectures try compiling this with their Java 6 JDKs?
