Yes you are because HashMap.hash(Object) was changed.

  That is only matters if your keys had badly distributed hashes in the first place.

    Uhm no. The hash code of my keys may be perfectly distributed but then HashMap#getNode comes along and masks most of my bits away. HashMap#hash(Object) is supposed to make the impact of the masking less bad.

      If your hashes are perfectly distributed, as in each bit having a 50% probability of being 1, independent of all other bits, then the low order bits will be just as random as the high order bits, no "making the impact less bad" required.
