> The issue is in file FilterExprOrExpr.java and FilterNotExpr.java.
> I posted a review for you at
> https://reviews.apache.org/r/10752/
> I think there is a bug related to sharing of an array of integers. Also, one
> algorithm step takes O(DEFAULT_BATCH_SIZE) time always. If
> n<<DEFAULT_BATCH_SIZE then this is a performance issue.
