ESB Mule Client staring with xml-properties fails - esb

Question

I use Mule 3.x
I have a code that tests MuleClient connectivity.
This test is ok and works proper way:
public void testHello() throws Exception
{
MuleClient client = new MuleClient(muleContext);
MuleMessage result = client.send("http://127.0.0.1:8080/hello", "some data", null);
assertNotNull(result);
assertNull(result.getExceptionPayload());
assertFalse(result.getPayload() instanceof NullPayload);
//TODO Assert the correct data has been received
assertEquals("hello", result.getPayloadAsString());
}
But this tes is not ok - it fail with an connection exceptions:
public void testHello_with_Spring() throws Exception {
MuleClient client = new MuleClient("mule-config-test.xml");
client.getMuleContext().start();
//it fails here
MuleMessage result = client.send("http://127.0.0.1:8080/hello", "some data", null);
assertNotNull(result);
assertNull(result.getExceptionPayload());
assertFalse(result.getPayload() instanceof NullPayload);
//TODO Assert the correct data has been received
assertEquals("hello", result.getPayloadAsString());
}
The 'mule-config-test.xml' is used in both tests, the path for this file is ok, i checked.
This is error message I have in the end:
Exception stack is:

I think the problem is in what you're not showing: testHello_with_Spring() is probably executing while Mule is already running. The second Mule you're starting in it then port-conflicts with the other one.
Are testHello() and testHello_with_Spring() in the same test suite? If yes, seeing that testHello() relies on an already running Mule, I'd say that would be the cause of port conflict for testHello_with_Spring().
