> I have just migrated a very outdated Spring backend to Spring 5 and with it upgraded CXF to first 3.3.2 and just now 3.3.3. I have a REST service class defining two different methods with the same path defined via {{javax.ws.rs.Path}} annotation, differentiated by {{javax.ws.rs.HEAD}} and {{javax.ws.rs.GET}} annotations. Both methods are annotated with {{@Produces(MediaType.APPLICATION_OCTET_STREAM)}}.
> When this method is called I get (redacted):
> {{WARN  [JAXRSUtils.compare:129] Both ServiceRestImpl#getFile and ServiceRestImpl#getFileAsHeadRequest are equal candidates for handling the current request which can lead to unpredictable results}}
> The differentiation works: HEAD requests are handled by the {{@HEAD}} annotated method and GET requests by the {{@GET}} annotated one (this has always worked). Therefore the warning is false but will severely clutter production log output, possibly affect performance.
> Relevant dependencies:
> * Spring framework 5.1.8
> * "org.apache.cxf", "cxf-rt-rs-service-description", "3.3.3"
> * "javax.servlet", "javax.servlet-api", "4.0.1"
> * "javax.ws.rs", "javax.ws.rs-api", "2.0.1"
> I'd appreciate support. May be linked to:
> * CXF-7670
> * CXF-6684
