      Description

        The fix for 6774607 was insufficient. Fix it correctly this time by using compressed pointers for linking up the overflown objects. The old fix in 6774607 was still vbulnerable in the case where the overflown object was an object array whose size is
        larger than ParGCArrayScanChunk.
