I have a REST resource which consumes multiple Http methods (for example GET, POST and PUT). If I send OPTIONS request to resource and I expect to receive Allow Http header with this content:

Allow: GET,POST,PUT,OPTIONS

That does not happen because I receive header which contains only two methods one of them is OPTIONS.

Allow: GET,OPTIONS

I have try multiple implementations and only camel-restlet works as I expect. These components contain bug:

• camel-undertow
• camel-servlet
• camel-jetty
• camel-netty4-http

Reproducer: https://github.com/osmman/camel/commit/0411f070f75e5b0a26a4b9ea371824f648d9b508

restConfiguration().component("undertow");
rest("/v1/")
    .get("resource")
          .to("mock:options")
    .post("resource")
          .to("mock:options")
    .put("resource")
          .to("mock:options);
