[jdk11u-dev] RFR: 8331142: Add test for number of loader threads in BasicDirectoryModel [v3]

[Andrew Lu]

> I backport this for parity with 11.0.25-oracle.
> The test is limit to Windows, so backport with JDK-8331495 together, also backport with the new issue JDK-8331999
> 
> threads.addAll(Stream.generate(() -> new Thread(new Scanner(fc)))
>                                  .limit(NUMBER_OF_THREADS)
>                                  .toList());
> change to as not supported in 11.
