Key: CAMEL-4994
URL: https://issues.apache.org/jira/browse/CAMEL-4994
Project: Camel
Issue Type: Improvement
Components: camel-spring
Affects Versions: 2.9.0
Reporter: alex hutter
Priority: Minor
If the org.apache.camel.Consume annotation is used on a method that is not
public (e.g. default visibility), then the following exception will be thrown
every time a message is delivered to that consumer and the message will
roll-back with the consumer never invoked.

I appreacate that this not specifically a bug, so I am filing this as an
improvement. However this is a REALLY misleading error message. A more
specific error message would be greaty appreaceated and save a lot of time.
Thanks.
