NullPointerException thrown when gamepad getting disconected on LWJGL3

Reference to issue in the forum with a possible fix suggested:

Possible fix can be adding this check

if (!glfwJoystickPresent(entry.getKey())) {
    continue;
}

after this line:

jmonkeyengine/jme3-lwjgl3/src/main/java/com/jme3/input/lwjgl/GlfwJoystickInput.java

Line 128 in 7b0471c

for (final Map.Entry<Integer, GlfwJoystick> entry : joysticks.entrySet()) {

I also noticed logger is initialized wrongly in :

jmonkeyengine/jme3-lwjgl3/src/main/java/com/jme3/input/lwjgl/GlfwJoystickInput.java

Line 52 in 7b0471c

private static final Logger LOGGER = Logger.getLogger(InputManager.class.getName());

it should be

private static final Logger logger = Logger.getLogger(GlfwJoystickInput.class.getName());
