    Why re-invent the wheel here, guava interners is well battle tested, and exists already.

> 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.
