EVALUATION Missing reference processor instance from marking oop closure resulting in calls to ReferenceProcessor::discover_reference() to be skipped. Also we need to treat the discovered reference lists as roots during incremental pauses so that if a reference on one of these lists is copied during a pause then we update the discovered ref list with that object's new location.
