In case anyone was curious I finally noticed that Apache Harmony now has implementations of this. Being Apache licensed, I believe I'm completely in the clear to take and modify the Harmony version to make it play well in GWT.
There's seems to be some strange behavior in not being able to override both TreeMap and AbstractMap... when GWT compiles TreeMap, it does not use my version of AbstractMap so it some things expected to be inherited in the new TreeMap are not there. Folding in the inherited code gets around this. I also had to remove clone() and readObject/writeObject serialization, and then it basically works. Performance seems acceptable, though I haven't done exhaustive testing, just some basic benchmarks. It would be really nice if this was part of GWT, the business of super- source JRE overriding is messy, and I'd rather not have it part of my project. There's not a lot else from 1.6 that makes sense for GWT (concurrency, etc), but in my opinion NavigableMap is all the stuff that SortedMap forgot, and they finally got around to adding.
