             # When reporting issues on macOS please specify if using
               ARM or x64.

*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.
