Bo Meng closed SPARK-14080.
---------------------------
    Resolution: Won't Fix

> Currently, the codegen of null check for Filter sometime generates code as followings:
> /* 072 */       if (!(!(filter_isNull2))) continue;
> It will be better to be:
> /* 072 */       if (filter_isNull2) continue;
