Thanks for the tip, I made another webrev (for archive) that shows the
proper diffs in ArrayCache / ArrayCacheConst:

Thanks!
In Renderer.java, you create the alphaLine and blkFlags refs as
Clean, but then you always put them back using indices of (0, 0) so
they will never actually be cleaned - is there a reason you don't
just use a dirty ref there?
Both alphaLine and blkFlags arrays must be zero-filled as these arrays
are storing accumulated values:
It is not possible to use a dirty reference in this case as both
allocated and returned array may contain garbage data (from the
IntArrayCache).
D'oh! I guess that was obvious. I wasn't thinking of the fact that
dirty caches can initially return a non-zero-filled array - the fact
that they clean on "put" is only half of their zero guarantee...
Other than that question, I don't see any problems with the fix...
Ready to go ?
or I need another reviewer, phil ?
Ready from my end. Phil?
