allowContextMapAll option in native mode

The allowContextMapAll option is not supported in native mode as it requires reflective access to security sensitive camel core classes such as CamelContext & Exchange. This is considered a security risk and thus access to the feature is not provided by default.

Additional Camel Quarkus configuration

Beyond standard usages described above, a trick is needed when using mustache templates from classpath resources in native mode. In such a situation, one needs to explicitly embed the resources in the native executable by specifying the include-patterns option.

For instance, the route below would load the mustache template from a classpath resource named template/simple.mustache:

from("direct:start").to("mustache://template/simple.mustache");

In order to work in native mode the include-patterns configuration should be set. For instance, in the application.properties file as below :

quarkus.camel.native.resources.include-patterns = template/*.mustache

More information about selecting resources for inclusion in the native executable could be found at Embedding resource in native executable.
