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.

ab725dba1d 7003554: (tiered) assert(is_null_object() || handle() != NULL) failed: cannot embed null pointer
