After sleeping on this issue I believe I understand what is happening.

When you build only tl/jdk the other pieces are assembled from the latest promoted JDK.
The new classes Jon added for 6708729/6439940 are not there yet, so they are not pulled
over.  The build fails later when trying to assemble tools.jar.

The following statement applies only to the jdk7/tl forest: until b30 is promoted, you _must_
build (at least) langtools plus jdk to get the new classes added.

You may build the rest (corba hotspot jaxp jaxws etc...) if you wish.
