Well I take it this isn't a Free JVM, as IcedTea6 is the only one I
know of that has
passed a JCK.  As you say JVM and not JDK, I take it we are talking about the
same TCK i.e. the JCK?

There was a JDK that had passed the JCK from which IcedTea6 was very
'substantially derived'.  It didn't mean there was no work to be done.

You can; check the OpenJDK TCK FAQ.  Using HotSpot as the VM
would count as substantially derived from OpenJDK.

I know; GNU Classpath went through all this before Harmony even existed.
