As we removed the extraneous `null` here we could also use the primitive
long type, right? I don't see any gain of using boxed types here. I see a lot
of boxing/unboxing down in this method, so it could be simply `int sid,
protocolVersion;` (this slightly falls into "the don't fix if..." adage, but we
can ignore this for once ;) ).
