> JMXControlService allows multiple mbeans (of a different type) registered for a single
``<type,alias,id>``.  The code below passes.
> When tweaked to use the JsonControlService it throws an ISE as noted in the comments
below.
> Which behavior is correct?  Does JsonControlService need to be enhanced?
> ```
>     @Test
>     public void testMultiBeanSameId() throws Exception {
>       
>         ControlService cs = new JMXControlService(DOMAIN, new Hashtable<>());
>         // ControlService cs = new JsonControlService();
>         
>         MyControlX myControlX = new MyControlX();
>         MyControlY myControlY = new MyControlY();
>         String type = "stream";
>         String id = "a";
>         String alias = "myStream";
>         String controlIdX = cs.registerControl(type, id, alias, MyControlXMBean.class,
myControlX);
>         // following registerControl throws ISE when using JsonControlService as its
>         // limited to a single registration for a <type,alias> pair.
>         // note: it ignores the id.
>         String controlIdY = cs.registerControl(type, id, alias, MyControlYMBean.class,
myControlY);
>         assertTrue(controlIdX, !controlIdX.equals(controlIdY));
>         assertTrue(cs.getControl(type, alias, MyControlXMBean.class) instanceof MyControlXMBean);
>         assertTrue(cs.getControl(type, alias, MyControlYMBean.class) instanceof MyControlYMBean);
>         cs.unregister(controlIdX);
>         cs.unregister(controlIdY);
