Intermittent NoSuchBeanException in a Camel Route Test

[fordm]

Hi,

I've got a pretty simple Blueprint Camel route, e.g.

<blueprint>
<Code omitted for brevity>
<camelContext id="blueprintContext"
xmlns="http://camel.apache.org/schema/blueprint";>
        <template id="producerTemplate" />
        
        <route id="myRoute">
                <from uri="fabric:key:queue" />
                <split parallelProcessing="true">
                        <simple>${body.getMyRequest}</simple>
                        <log message="Single My Request is ${body}"/>
                        <to uri="direct:processMyRequest" />
                </split>
        </route>
</camelContext>
</blueprint>

When deployed into a Fuse ESB Fabric messages route correctly. Like a good
developer, I've written a route test (which extends
CamelBlueprintTestSupport), e.g.

public class MyRouteTest extends CamelBlueprintTestSupport {
        private static final String MESSAGE = "Some message";

        @Produce
        protected ProducerTemplate producerTemplate;

        @Test
        public void messageSuccessfullyRouted() throws Exception {
                getMockEndpoint(MOCK_TO_QUEUE).expectedMessageCount(1);
                producerTemplate.requestBody("fabric:key:queue", MESSAGE);
                assertMockEndpointsSatisfied();
        }

        @Override
        protected String getBlueprintDescriptor() {
                return "/OSGI-INF/blueprint/blueprint.xml";
        }

        // Code omitted for brevity
}

Now, running the test (as part of my maven build) occasionally gives me a
NoSuchBeanException:

org.apache.camel.NoSuchBeanException: Found bean: producerTemplate in

Anyone got any ideas?

Many thanks
