There's a bug in `SSLEngine`/`SSLSocket` that prevents configuration callbacks from working as originally imagined.  I hate working around it.

The subclass constructor now calls `super()`, which then calls back to the `configure*()` methods, but you can't pass any parameters.  One of these days this should be fixed.  

I find it easier to just copy `SSLEngineTemplate.java` instead of `extends`.  

I've worked around it to remind myself this needs to be fixed someday.
