Description
getDisplayMode() returns null for the default graphics device on linux-arm (and Linux VM).
According to Oracle docs the returned value can not be null.
The issue can be seen with this code:
GraphicsDevice gd = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
DisplayMode dm = gd.getDisplayMode();
if(dm == null) {
System.err.println("DisplayMode is null");
} else {
System.err.println("DisplayMode=" + dm.toString());
}
We do not observe the issue on linux-i586.
We have several functional tests failing because of this issue.
