Description
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.
Comments
AlexanderZ, the fix is required for 8u60 as well.

I'm sending GO to this PIT. In return, I'll set this bug to P2 and hope it will be fixed by the next PIT.
