Not for the libraries but for the applications.

The application developers just use the library.

Whether that library is using the same OS function or are #ifdef vms
does not matter for the application programmers.

That stuff is useful.

Emulating reading from /dev/urandom may not be as useful.

Java 8 is available for VMS. (Itanium, Alpha is stuck on Java 5)

Java 11 is not.

And Java 17 will not be when it is released tomorrow.
