No. Load reference barriers don't have oopmap.
And the slow path runtime call of LRB is a leaf call which doesn't have oopmap and cannot suspend in safepoint.
Thanks,

Subject:Load reference barriers and safepoints
Do load reference barriers may reach a safepoint? Or slightly
different question: Does Hotspot need to keep an accurate stack map at
the point of the barrier?
I'm just curious, no particular reasons for me to ask.
