Description: This issue is try to tune the HashJoin implementation codes.
At right or full join type , the HashJoinProbe will create a List<Integer>
member to record the unmatched composed indexes. It can be replaced by a
primitive IntArrayList without box/unbox operation ,also benefits the GC if
there's more unmatched items.
