Review comment:
<!--new_thread; commit:7bf9d2048e8d568ee9280629db391775cc490358;

This is actually incorrect right now, since as coded the key type might not
be a primitive type. However as I mentioned in Schema.java, I think it would be
better to change the key type to be a TypeName, in which case this logic will
be correct.
