The test looks good with one minor typo in the constant field name (see below).
I verified that it fails on Linux and
Mac (as I suspected), so you will need to limit the test to running on Windows.

You can add an `assumeTrue(PlatformUtil.isWindows());` here to ensure that the
test only runs on Windows.
