        To reproduce, attach to a Linux system with Gnome 3 (OEL 7 or Ubuntu 14) 2 different monitors, be sure you have the extended screen and then run the test with JDK9 b66 (or something since b63 I believe).
        On my system, first of the (LCD) monitors does warn about suggested parameters of the screen on every display mode change, and the second one would be immediately detached.

        We may consider this as a regression introduced after b62 with a fix to JDK-8051617 -- but then again, before the fix, this test just didn't run as Fullscreen mode was reported as not supported, so it's hardly exactly a regression.

        Obviously, the test makes further multimonitor testing impossible, and the issue should be fixed asap.
