“Cannot reproduce” - is Java deterministic multithreading possible?

Question

Is this possible to run multithreaded Java application in a deterministic fashion? I mean to have always the same thread switching in two different runs of my application.

Answer 1

No it is not possible (other than to simulate it yourself) to use multiple threads interleaving in the same way each time around. Threads are not designed to do that.

If you want deterministic results, don't use threads.
