I am trying to build a test setup containing two Sprin Boot Applications. 
Both of the Apps have a seperate class. 

Both Apps look something like this: (but are different, seperated classes)

```
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.*;

@RestController
@EnableAutoConfiguration
public class MySpringBootApplet {

    @RequestMapping("/")
    public String home() {
        System.out.println("home() called ..");

        try {
            Thread.sleep(1000);
        } catch (InterruptedException ex) {
            Thread.currentThread().interrupt();
        }

        System.out.println("waited ..");

        return "<!DOCTYPE html><html><body><h1>Test</h1><p>Hello world!</p></body></html>";
    }

```

Both are started with 

```
SpringApplication app = new SpringApplication(MySpringBootApplet.class);
app.run();

```

When the second app is started, I get the error:

> 
> org.springframework.jmx.export.UnableToRegisterMBeanException: Unable
>  to register MBean
>  [org.springframework.boot.actuate.endpoint.jmx.DataEndpointMBean@6a48a7f3]
>  with key 'requestMappingEndpoint'; nested exception is
>  javax.management.InstanceAlreadyExistsException:
>  org.springframework.boot:type=Endpoint,name=requestMappingEndpoint
> 
> 
> 

I can imagine that this is because both applications try to register with the same interface. But how do I separate this? 

Thanks for your help
