Hello. Please review the fix for jdk/client. Bug: https://bugs.openjdk.java.net/browse/JDK-8238936 Fix: http://cr.openjdk.java.net/~serb/8238936/webrev.00
Our Robot's peers have an incorrect assumption that all graphics devices passed to the constructor are supports. - On windows, we simply ignore this device(even if the device is a custom not "real" device) because we know we can move the mouse on every screen. - On macOS, we cast this device to the internal graphics device and get ClassCastException. - On Linux, we try to access the passed graphics device and its config via JNI and get a crash. In the fix we throw AWTException if the device is not of the class of the real graphical device used by the AWT toolkit + small cleanup -- Best regards, Sergey.
