> Custom resource comparator not called on sub-resource classes
> -------------------------------------------------------------
>
> Key: CXF-7333
> URL: https://issues.apache.org/jira/browse/CXF-7333
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 3.1.11
> Environment: Mac OS X 10.12.4
> Oracle Java Runtime 1.8.0_60-b27
> Tomcat 8.5.11
> debugged and executed via Eclipse Neon.3 Release (4.6.3)
> Reporter: Thomas Iguchi
> Assignee: Sergey Beryozkin
> Priority: Major
>
> I created a custom `ResourceComparator` according to the documentation:
> https://cxf.apache.org/docs/jax-rs-basics.html#JAX-RSBasics-Customselectionbetweenmultipleresourcesoroperations
> Its method for comparing resource classes gets called just fine, but the one
> for comparing two instances of OperationResourceInfo never gets called when I
> want to invoke a method of a sub-resource class such as the following example
> for illustration:
> ```
> @Path("subpath")
> public class SubResource {
> @POST
> public Response createSomething() {
> // ... this is the method I want to compare, since there's a
> "competitor" with the same method signature in an abstract base class
> }
> }
> @Path("/rootpath")
> public class RootResource {
> @Path("subpath")
> public SubResource subResource() {
> return new SubResource();
> }
> }
> ```
> I stepped through the CXF code and could narrow down the problem to the
> following line of code:
> In line 48 of `org.apache.cxf.jaxrs.model.OperationResourceInfoComparator`
> the looked up custom comparator from the environment returns as `null`. It
> appears as if the message endpoint object for the sub-resource class contains
> incomplete information about the environment.
