Description

When running a YAML route using camel-jbang, it fails to find the class for a Java bean in the same directory. However, the equivalent route written in Java DSL runs the route without errors.

The attached tarball contains a simple bean and equivalent routes in Java and YAML.

To see the failures, run the YAML route:
