bug: https://bugs.openjdk.java.net/browse/JDK-8210886 webrev: http://cr.openjdk.java.net/~prr/8210886/
the legal file xwindows.md gives attribution for several source files from the X11 distribution which in fact are not present anywhere. Some really ancient (1.5 ?) version of Oracle JDK had some of them and extitil.h was removed during the JDK 9 cycle since it was unused but that didn't stop it being listed in the legal file. -phil.
