If an object is only reachable from the stack of a VT and the VT itself is not followed then we don't find that object either. But as I said a VT should be found via the object it is parked on, or via the scheduler. So is it the case that the current logic will not follow the stack of an unmounted Virtual thread? If so that seems wrong - especially if a mounted VT would find those objects. A VT is not a GC root but now I'm unsure exactly what that means. ------------- PR Comment: https://git.openjdk.org/jdk/pull/13254#issuecomment-1504443345
