        Description

        VM should reserve protected page below heap for compressed oops implicit null checks if zero base can not be used.
        But the changes for 6791178: "zero based compressed oops " change code in such way that the page is not reserver
        which could again cause 6716785: "implicit null checks not triggering with CompressedOops" problem.
