Yes and no.

The new Loom threads will be much lighter weight than the original Java green threads. Further, the entire IO infrastructure of the JVM is being reworked for Loom to make sure the OS doesn't block the VM's thread. What's more, Loom does M:N threading.

Same concept, very different implementation.

So, with Loom now we can tell exactly in which order theses threads were executed as it's not up to OS to decide thread execution order anymore?

Everything I've ever been taught about multi-threading, parallelism, and concurrency says never to make any assumptions about execution order. What are you doing that your care about it?

Replay system.
