The change itself looks good. But wouldn't it be better to do a clean backout of [JDK-8194154](https://bugs.openjdk.org/browse/JDK-8194154) and then add the test that user.dir can be changed in JDK8 with a different issue?

Or would it at least be possible that the test is not shown as renamed but rather as a deletion of the old test and the addition of a new test? (Not sure whether that's something that git did automatically or whether you can change this)
