Christopher Tubbs commented on ACCUMULO-4681:
---------------------------------------------

Having a static "of" method on both seems useful to me. I'd probably drop the 
reflection, though, and simply provide two instances of the 
"getNext(Table|Namespace)Id", which share a common implementation. Or... just 
use it like {{Table.ID.of(Utils.getNextId())}} and 
{{Namespace.ID.of(Utils.getNextId())}}.

> Create WeakReference Map to replace Table.ID constructor

> Taken from feedback on the PR #279:
> Could maybe avoid duplicates by making constructor (of Table.ID) private and 
> doing Table.ID.of(tableId), which draws from an internal WeakReference map.
> If the object deduplication in KeyExtent is still valid, this can be pushed 
> down to the Table.ID and Namespace.ID classes, replacing the optimization in 
> KeyExtent.
