   @essobedo to reproduce the problem:
   bundle 1
   
   ```
   package my.test;
   
   public interface MyService {
       String myMethod();
   }
   ```
   ```
   package my.test;
   
   public class MyServiceImpl implements MyService{
       @Override
       public String myMethod() {
           return "test1";
       }
   }
   ```
   in blueprint
   ```
   <bean class="my.test.MyServiceImpl" id="myServiceImpl"/>
   <service ref="myServiceImpl" interface="my.test.MyService"/>
   ```
   
   bundle 2
   in blueprint
   
   ```
       <reference id="myService"
                  interface="my.test.MyService"
                  timeout="30000" availability="mandatory"/>
       <camelContext xmlns="http://camel.apache.org/schema/blueprint" id="mytest">
           <route>
               <from uri="timer://letsgo?repeatCount=1"/>
               <to uri="bean:myService?method=myMethod" />
               <to uri="log:test" />
           </route>
       </camelContext>
   ```
   @paul-mcculloch I was able to partially solve the problem using
   `<to uri="bean:my.test.MyService?method=myMethod" />`
   or if you need to set some header
   ```
               <setHeader name="myCustomHeader">
                   <method method="myMethod()" beanType="my.test.MyService"/>
               </setHeader>
   ```
   but sometimes I get a class missing error, I think it depends on the order of loading bundles (maybe as a fix use different start-level), or using lazyStartProducer https://camel.apache.org/components/4.10.x/bean-component.html
