I'm having some trouble with this statement. Working backwards from L836, I see the nullptr check on L826 and the check for non-virtual thread and bail on L827 and L831. However, if we saw nullptr on L826 and we have a virtual thread, then we can get to L836 even when we started off with a null java_thread. So I guess I'm not sure what point you're trying to make with the statement. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/26287#discussion_r2231702449
