> CellComparator.compareStatic(Cell a, Cell b) compares type wrongly.
> {code}
> //type
> c = (0xff & a.getTypeByte()) - (0xff & b.getTypeByte());
> if (c != 0) return c;
> {code}
> In the normal case it should be the other way
> {code}
> // Compare types. Let the delete types sort ahead of puts; i.e. types
> // of higher numbers sort before those of lesser numbers. Maximum (255)
> // appears ahead of everything, and minimum (0) appears after
> // everything.
> return (0xff & rtype) - (0xff & ltype);
> {code}
> Found this issue while replacing KVComparator to use CellComparator.

> Could you confirm this once? Currently PrefixTree code path uses this
> compareStatic method.
