Currently the jtreg test javax/swing/JFileChooser/4847375/bug4847375.java fails on Windows (seems it is a Windows only test anyway).
We run into this assertion (on Windows 10, also on Win server 2016 so it is an issue on variuos Windows versions) :

----------System.out:(0/0)----------
----------System.err:(35/2642)----------
