I have an unexpected 'no match found' and we dont understand this error.
The interface I am mocking is the following. The notifyTvStatus method is invoked by another thread than the one the thread wich sets the 'expects' at the mock object.

public interface TvUpdateListener {
   public void notifyTvStatus(final String ipAddress, final boolean isStandby, final short channel);    
}

I wrote the following testcase:

/**
 * Test the selection of multiple channels
 */
public void testChannelSelection() {
   
   // set up
   final Mock mockTvListener = mock(TvUpdateListener.class);

   mockTvListener.expects(atLeastOnce()).method("notifyTvStatus").with(eq("172.16.30.183"), eq(false), eq(2));
   mockTvListener.expects(atLeastOnce()).method("notifyTvStatus").with(eq("172.16.30.183"), eq(false), eq(1));

       // Select channel 1
        tvProxy.selectChannel(1);

}

I expect the selectChannelCommand to invoke a callback on a subscribed TvUpdateListener. The asynchronously callback is done by a different thread. When this callback arrives at the mock object we get an unexpected error:

org.jmock.core.DynamicMockError: mockTvUpdateListener: no match found

I don't understand why the mock object detects a mismatch.
Does anybody has a solution/explanation?
