Hi, Laurent.
I am not an expert here but just my 50 cents.
This optimization shall take place only if it is really hotspot. But if
it is a really hotspot - probably it would be better to remove these
array/object allocation at all and use plane bytes?
I see that some methods which take it as argument doesn't use them. And
most of the time we pass AATileGenerator and abox[] to the same methods,
so it could be merged?
Also I suggest to use jmh for java micrbenchmarks.

So your test will be:
