3aaa5fb06d 7016112: CMS: crash during promotion testing 
Also reviewed by mikael.gerdin@oracle.com; stdlib:qsort() does byte-by-byte swapping on Windows. This leads to pointer shearing. Fix is to implement a quicksort that does full pointer updates.

a08e1ce906 7009266: G1: assert(obj->is_oop_or_null(true )) failed: Error 
A referent object that is only weakly reachable at the start of concurrent marking but is re-attached to the strongly reachable object graph during marking may not be marked as live. This can cause the reference object to be processed prematurely and leave dangling pointers to the referent object. Implement a read barrier for the java.lang.ref.Reference::referent field by intrinsifying the Reference.get() method, and intercepting accesses though JNI, reflection, and Unsafe, so that when a non-null referent object is read it is also logged in an SATB buffer.
