The change looks fine overall.
A few questions: did you have a measurable speedup by keeping the
hashcode around (if you tested with that case)?
Could you also experiment with separate key and value arrays
(it would help a lot for the cases where one of the two is not a
reference during GC)?
It would also be nice to try a variation with a 0 NO_SLOT value, because
it means you don't have to spend time initializing it (and it would mean
starting allocations of slots at 1 or adding compensation code, though).

Thanks!
