Sergey Beryozkin resolved CXF-5360.
-----------------------------------

       Resolution: Won't Fix
    Fix Version/s: 2.7.7
         Assignee: Sergey Beryozkin

Unfortunately not possible to fix in CXF 2.7.x, will work in CXF 3.0.0 (with the beat to be released soon). In meantime: use ResourceComparator  or subresources if possible

> The problem: the resource is selected incorrectly when multiple classes can 'visually' handle request. For example if we have two classes
> {code}@Path("/") class Foo {
>   @GET @Path("bar") public String bar() { return "bar"; }
> }
> @Path("/") class Real {
>   @GET @Path("hello") public String hello() { return "hello"; }
> }{code}
> and their instances are registered in this order (e.g. in jaxrs:serviceBeans), when I GET the "/hello" path, the Foo will be selected, while it is not even able to handle this request.
> The starting point to investigate the problem is org.apache.cxf.jaxrs.utils.JAXRSUtils.selectResourceClass(List<ClassResourceInfo>, String, MultivaluedMap<String, String>, Message), where 'candidateList' variable is filled incorrectly. Unfortunately I'm not so familiar with CXF code to provide a patch, but resource class must be selected basing on full class description (all methods and annotations must be taken into account).
> Why this is a problem: except obvious reason (unexpected behavior), this bug disallows to make REST service modular. For example we may want to provide different feature sets for different servers. Right now it is not possible to implement.
