We need your help in testing new Selector implementation on Windows [1]: * The implementation of the Selector API on Windows has been replaced in JDK 17 b22 with a new more scalable implementation [2]. * The old select based Selector implementation has been the default since Java 1.4 (2002) so replacing it is a significant change. * It would be really helpful to get more testing of the new implementation before the fork for Rampdown Phase One on June 10th.
