java.lang.ThreadBuilders and java.lang.ThreadBuilders.newVirtualThread() are not public

[Rick Hendricksen]

Hi,

We have implemented a Discrete Event Simulator, and we want to use virtual threads to write our business logic (that uses the DES) in a more readable way. This business logic has a lot of blocking operations, so it seems to be a good fit for virtual threads. However, we must ensure that all those virtual threads run on the same carrier thread, because the simulation has to be deterministic. We also often run multiple separate simulations in parallel, so it’s important that virtual threads end up on the right scheduler. This means we need to use our own scheduler.

To achieve this we call newVirtualThread with reflection (and we have to add --add-opens), and that works. But we'd like to have a solution that continues working in future java versions, so we'd like this use case to be officially supported. Can this method become public?


Best regards,

Rick Hendricksen
