REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
@Override
    public void handle(KeyEvent evt)
    {
        switch(evt.getEventType().getName())
        {
            case("KEY_PRESSED"):
                System.out.println("key pressed");
                break;
            case("KEY_RELEASED"):
                System.out.println("key released");
                break;
            default:
        }
    }
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Workaround would be to use consecutive if/else if conditions, but i couldn´t manage to run this with strings in switch
