Weird error with expectedBodiesReceived

[Sylvester]

Hi,
Earlier the following was running just fine. Out of the blue it started 
giving me this error:
expectedBodiesReceived (List) not applicable to 
expectedBodiesReceived(String). I understand what it means, but:

  1. The examples on the camel website all have strings, so this should
     not be a problem.
  2. Why should it stop working just like that? ( I had played around
     with the pom, could that be it?)

public void testSendingAMessageUsingMulticastReceivesItsOwnExchange() 
throws Exception {
       MockEndpoint x = getMockEndpoint("mock:x");
       MockEndpoint y = getMockEndpoint("mock:y");
       MockEndpoint z = getMockEndpoint("mock:z");
       
       x.expectedBodiesReceived("answer");
       y.expectedBodiesReceived("answer");
       z.expectedBodiesReceived("answer");
       
       
       z.expectedMinimumMessageCount(100);

       sendBody();
//        z.assertIsSatisfied();
       assertMockEndpointsSatisifed();
       
   }
