OPTIONS requests returns 404 Not Found

Hello,

for resources with a template variable amidst of the URI-template an OPTIONS request returns 404 Not Found.
E.g. @Path("/customers/

{custid}/phonenumbers")
or @Path("/customers/{custid}

/phonenumbers/

{id}

")

For these resources requests for not implemented methods returns 404 Not Found too, while I receive 405 Method Not Allowed for a resource with
@Path("/customers") or @Path("/customers/

{custid}

").

With best regards
Andreas Schneider
