SwaggerFeature: SetScannerInterceptor causes NPE in Fuse 6.2

Issue

• We run a cxfbean: component as a provider that runs behind a camel jetty consumer. Upgrading to Fuse 6.2.0 create a NullPointerException when calling via the jetty endpoint.

• The cause is that there is a SwaggerFeature added to the default CXF bus which assumes HTTP.CONTEXT is available on the camel message context, but the Jetty component doesn't set this, so this line in SetScannerInterceptor produces an NPE.

 mci.getServletContext().setAttribute("SCANNER", beanConfig);

(mci.getServletContext() is null)

• The workaround is to stop the bundle fabric-cxf that registers the SwaggerFeature, but this is not convenient and doesn't allow us to use this feature.
