I would be careful of over optimizing this. They let reason for the use of
this class was to reduce the long autoboxing. Itâs used throughout the code
base where concurrent hash map used to be.
It comes also from Bookkeeper where itâs heavily used.
I think we have bigger fish to fry in artemis than over optimizing this.---
