When the user presses Escape
button, the following code is executed in LinuxKeyboardReader.keyPressed()
:
// escape is never returned as 27, instead it sets some state as a // modifier key if (key == KeyEvent.VK_ESCAPE) { // toggle the flag escPressed = !escPressed; queue.add(null); ^^^^ return; }
The LinkedBlockingQueue
does not accept null
value as the item, to the call queue.add(null)
causes explicitly thrown NPE:
public boolean offer(E e) { if (e == null) throw new NullPointerException();
The java.awt.EventDispatchThread
catches, logs and ignores the exception, so no client crash happens due to it.
But the FWD code after the call are not executed due to this exception, this result in that the next keyboard command is interpreted in some unexpected way.
