### Question:
JMXFactory { public static ObjectName createSimpleMBean(String className, String objectNameStr) { log.info("Create the {} MBean within the MBeanServer", className); log.info("ObjectName = {}", objectNameStr); try { ObjectName objectName = ObjectName.getInstance(objectNameStr); if (!mbs.isRegistered(objectName)) { mbs.createMBean(className, objectName); } else { log.debug("MBean has already been created: {}", objectName); } return objectName; } catch (Exception e) { log.error("Could not create the {} MBean. {}", className, e); } return null; }  static ObjectName createMBean(String className, String attributes); static ObjectName createObjectName(String... strings); static ObjectName createSimpleMBean(String className,
			String objectNameStr); static String getDefaultDomain(); static MBeanServer getMBeanServer(); @SuppressWarnings("unchecked") static boolean registerNewMBean(String className,
			Class interfaceClass); @SuppressWarnings("unchecked") static boolean registerNewMBean(String className,
			Class interfaceClass, ObjectName name); @SuppressWarnings("unchecked") static boolean registerNewMBean(String className,
			Class interfaceClass, String name); String getDomain(); void setDomain(String domain);  }### Answer:
@Test public void testCreateSimpleMBean() { System.out.println("Not yet implemented"); }
