NPE during camel route test

I am trying to test camel route, and below are the annotations on my test class.

@RunWith(CamelSpringBootRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
@DirtiesContext(classMode = ClassMode.AFTER_EACH_TEST_METHOD)
@DisableJmx(true)
public class PortfolioTncRouteTest {
      ....
      ....
      @Test
public void portfolioTncRouteTest() throws Exception {
    Mockito.when(clientApiService.search(Mockito.any(TxnChangeLog.class))).thenReturn(txns);
    Mockito.when(cache.getValue("frequencies", "8")).thenReturn("Monthly");
    Mockito.when(cache.getValue("currencies", "1002")).thenReturn("USD");
    Transaction transaction = new Transaction();
    transaction.setRefStatusId(2);
    Mockito.when(transactionService.findTransaction(Mockito.any(), Mockito.any())).thenReturn(transaction);
    producerTemplate.sendBody(txns);
    mock.expectedMessageCount(1);
    mock.assertIsSatisfied(30000);
}
}

My test passes but at the console I keep receiving below error message.

How do I resolve this error? Is it the error during my route processing?

This NPE is fixed in Camel 3.0.0-M3 which is to be released soon.
