Java - GetLockingState() won't update

问题

Found bug Java Bug

"CAPS" doesn't update. I want it to be actively checking the locking state but it only checks it once and stores true/false in "CAPS" but if you hit caps lock it doesn't change the boolean stored in CAPS.

Thread capsCheck = new Thread(() -> {
    while (true) {
        boolean CAPS = Toolkit.getDefaultToolkit().getLockingKeyState(KeyEvent.VK_CAPS_LOCK);

        if (CAPS) {
            System.out.println("Caps enabled");
        } else {
            System.out.println("Caps disabled");
        }
        try {
            Thread.sleep(2000);
        } catch (Exception e) { }
    }
});
