> The problem appears in version 4.3.1 and in revision 1498027.  I
> attached a two-line patch that fixes it.
> In method "FuzzySet.getNearestSetSize", the loop over
> "usableBitSetSizes" keeps overriding "result" with
> "usableBitSetSizes[i]".  Therefore, only the last written value is
> visible out of the loop and all the other writes and iterations are
> not necessary.  The patch iterates from the end of "usableBitSetSizes"
> and breaks the first time when "result" is set.
