@franz1981 done, also spotted a few wasteful bits in AMQP as well, where it
went from String to SimpleString, back to String and back to SimpleString (or
repeatedly created SimpleString from String), so cleaned that up .

> The core protocol produce a huge amount of StringValue/SimpleString instances
> during CoreMessage decoding of SessionSendMessages.
> Often these instances are the same during the lifetime of a client/server
> connection: providing efficient interners would help to reduce the GC
> pressure, increasing the broker capacity/scalability.
