Incorrect 'channel' attribute in an endpoint method annotation

Reports incorrect channel attributes in endpoint method annotations: @Gateway, @ServiceActivator, @Filter, and so on.

Example:

  @Component
  public class MyComponent {}
     @Gateway(requestChannel = "requestChannel", replyChannel = "replyChannel")
     public void gateway() {...}

     @Gateway(
        requestChannel ="simpleBean",   // Bean must be one of these types: org.springframework.integration.MessageChannel,org.springframework.messaging.MessageChannel
        replyChannel = "unknownChannel")   // Cannot find channel
     public void errors() {...}

     @Bean
     public MyBean simpleBean() {...}
  }
