Get current keyboard layout using java

Question

I wrote code that changes the layout language on the PC until English is selected, the language changes, the key combination is correct, but the loop continues forever

        InputContext context = InputContext.getInstance();
        Locale curLocale = context.getLocale();
        
        while(!curLocale.equals(Locale.US)) {
            robot.keyPress(KeyEvent.VK_SHIFT);
            robot.keyPress(KeyEvent.VK_ALT);
            robot.keyRelease(KeyEvent.VK_SHIFT);
            robot.keyRelease(KeyEvent.VK_ALT);
            Thread.sleep(500);
            context = InputContext.getInstance();
            curLocale = context.getLocale();
        }

That is, the old layout value is written to curLocale
