Is this the TreeMap? If so, it's one class which they modified heavily
themselves
so that it worked as part of 1.6.

I didn't say it didn't work, I said it wasnt' likely to pass the TCK
without a lot of work.
You could of course link the Harmony class library up to HotSpot,
apply for the OpenJDK6 TCK
to certify that combination and prove me wrong.
