Bela Ban commented on JGRP-2481:
--------------------------------

Created new class {{IntHashMap}} which uses ints/shorts/longs etc as keys (and indices), and an array for the values.

> When we have lookup hashmaps, populated at startup, and not changed afterwards, we can use IdentityHashmaps, as a {{get()}} is constant.
> For keys with a contiguous range (e.g. {{[1 .. 20]}}), we might even use a simple array of keys and values, e.g. {{[K1,V1,K2,V2, ... Kn,Vn}}.
