      Description

      When generating a Swagger for the Rest Java DSL in Karaf with the camel-core-osgi bundle I'm receiving the following exception[1]

      It appears this is happening because the core/camel-xml-jaxb bundle does not import all the packages defined in the org.apache.camel.model.Constants.JAXB_CONTEXT_PACKAGES so it is unable to see the jaxb.index.

       

      I was able to get it to work by manually adding the packages to the camel.osgi.import property in the pom since the packages are not used anywhere else in the camel-xml-jaxb.  Doesn't seem like a great solution since it requires the pom to match the packages defined in Constants.JAXB_CONTEXT_PACKAGES.  Open to other suggestions.
