--------------------------------------
Summary: ControlService impls - need to enhance JsonControlService?
Key: QUARKS-155
URL: https://issues.apache.org/jira/browse/QUARKS-155
Project: Quarks
Issue Type: Task
Reporter: Dale LaBossiere
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);
}
```
