      Description

        The following change should be made in verify_remembered_set() in src/share/vm/gc/g1/heapRegion.cpp to protect against the crashes that can occur if the object (obj) in the 'to' region which is being printed here has been overwritten and is no longer a valid oop:

        739 _containing_obj->print_on(log.info_stream());
        740 log.info("points to obj " PTR_FORMAT " in region " HR_FORMAT, p2i(obj), HR_FORMAT_PARAMS(to));
        + if (obj->is_oop()) {
        741 obj->print_on(log.info_stream());
        + }
        742 log.info("Obj head CTE = %d, field CTE = %d.", cv_obj, cv_field);
