Description

This route worked fine in Camel 2.24.2 (and Spring Boot 2.2.1.RELEASE):

@Component
public class UuidRoute extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        from("seda:in")
            .setHeader("CorrelationId", method(java.util.UUID.class, "randomUUID"))
            .to("mock:out");
    }
}

but fails with Camel 3.0.0 (and Spring Boot 2.2.1.RELEASE (also with Spring Boot 2.2.2.RELEASE)) when the route is used:

Test to allow reproduction:

@RunWith(CamelSpringBootRunner.class)
@SpringBootTest
public class InvokeBeanNotCreatableBySpring {

    @Produce(uri = "seda:in")
    private ProducerTemplate template;
    @EndpointInject(uri = "mock:out")
    private MockEndpoint mockOut;

    @Test
    public void test() throws Exception {
        mockOut.expectedMessageCount(1);
        template.sendBody("");
        mockOut.assertIsSatisfied();
    }
