Thanks for the test case. There is one difference, though. Could you try replacing `new File(System.getProperty("java.home")).toPath()` by `Paths.get(System.getProperty("java.home"))`, which is how we create our `HOME_DIR`. If this makes a difference (meaning that it produces the exception) then you were right and I have to say sorry for my impatience.

I will try to debug, but I need to find some time first.
