> JDK-8047340 explicitly calls out BSD-like systems, should not we just exclude those systems
instead of enabling solely Linux?

> Assume.assumeFalse("Avoiding JDK-8047340 on BSD-based systems", Shell.FREEBSD || Shell.MAC);
> {code}
> However, I don't think this is the right fix. Shell on BSD-like systems is broken with
the TR locale. Shell class initialization happens only because StringUtils references Shell.WINDOWS.
> We can simply catch Throwable in Shell#isSetsidSupported instead of IOException. If we
want to be pedantic we can rethrow
> {code}
> if (!(t instanceof IOException) && !(Shell.FREEBSD || Shell.MAC))
> {code}
> With such a change the test can run unchanged.
