FULL PRODUCT VERSION :
java version "9.0.1"
Java(TM) SE Runtime Environment (build 9.0.1+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 10.0.16299.64]

EXTRA RELEVANT SYSTEM CONFIGURATION :
It is related to multimonitor environment. To reproducuce the bug you will need at least two monitors.

A DESCRIPTION OF THE PROBLEM :
Create a JFrame, setup it as undecorated, maximize it and try to move it to other monitors using the standard Shift+Win+<arrow> keyboard shortcuts. It stucks on 2nd monitor. Other (native) applications works as expected.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile the attached sample app.
2. Start it wit the "UNDECORATED" argument:
    java MainFrame UNDECORATED
3. Maximize it (click the Maximize button). It should appear on primary (left) monitor.
4. Press Shift+Win+Right to move it to 2nd monitor.
5. Press Shift+Win+Left to move it back primary monitor.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
It should be possible to use Shift+Win+<arrow> keyboard shortcuts to move window to all monitors.
ACTUAL -
It is not possible to use Shift+Win+<arrow> keyboard shortcuts to move window to all monitors. The window stuck on the 2nd monitor.

REPRODUCIBILITY :
This bug can be reproduced always.
