I have learned that hpack is not *required* by http2, but that any 
sensible implementation will use it because it reduces the amount of 
data sent over the wire.  In many cases that savings can be significant.

I'm sure that the jetty server included with Solr has hpack enabled by 
default.  I haven't seen anything to indicate that it's even 
configurable ... it may not even be possible to turn it off.

I've been able to work out why hpack is in its own jar.  It's used by 
both the client and the server.

Thanks,
