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