Apart from a few things being made final that weren't, and a flattening of a back-to-back Charset lookup in one of the constructors its mostly formatting cleanups.

Right, I'm not exactly sure why the more limited changes I attempted in 5f4e87f failed. In that change I simply changed the initialization order, which made the failing (closed) tests pass locally - but not in our CI. Since this is in initPhase1 there should be no concurrency possible.
