I will perform some benchs to see if it will impact positively on checks
and/or pattern matching based on equals: only in that case I will send a
separate improvement PR :+1:
> Reduce GC pressure due to String allocations on Core protocol
> -------------------------------------------------------------

> Key: ARTEMIS-1586

> Project: ActiveMQ Artemis

>
> 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.
