My first experience with JDK 9:

The following code didn't work anymore:

         if (UIManager.getLookAndFeel() instanceof WindowsLookAndFeel) {

On a windows machine it barked that I am not allowed
to access the class WindowsLookAndFeel.

I did the following workaround:

         if (LAF_ID.equals(UIManager.getLookAndFeel().getID())) {

I have mixed feelings towards JDK 9. It also
run 50% slower than JDK 8. I was running my usual
benchmark all of them were significantly slower.

I did these tests 2-3 months ago, maybe the
performance problem is now fixed. Dunno.
