With Camel 2.15.5 or with _SampleCamelRouter_ of content below, exception
doesn't occur.

@Component
public class SampleCamelRouter extends RouteBuilder {
@Resource CamelLogger camelLogger;
@Override
public void configure() throws Exception {

.transform(method("myBean", "saySomething"))

I didn't see anything in release notes in 2.16, 2.17, 2.18, or 2.19 that would
indicate there's a change in behavior from 2.15 in this regard. Either this is
a bug that should be fixed, or the change in behavior should be documented.
