-------------------------------
    Comment: was deleted

(was: 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.)
