Description

A Warning is logged on every JAX-RS call: " Both Object#method and Object#method are equal candidates for handling the current request which can lead to unpredictable results". This occurs even with no configuration errors (only one service with one method).

This bug seems to be introduced by commit d58606e554418899e905cd2f3bc7e8c465eff451.

org.apache.cxf.jaxrs.utils.JAXRSUtils#findTargetMethod uses a java.util.TreeMap with org.apache.cxf.jaxrs.model.OperationResourceInfoComparator. But java.util.TreeMap.put(K, V) calls compare(key, key) internally.

Test.java

    @Test
    public void testWarning() throws Exception
    {
        Message m = new MessageImpl();
        Exchange e = new ExchangeImpl();
        e.setInMessage(m);
        e.put(Endpoint.class, Mockito.mock(Endpoint.class));
        OperationResourceInfo k = new OperationResourceInfo(getClass().getMethod("toString"),
                new ClassResourceInfo(getClass()));
        k.setURITemplate(new URITemplate("template"));

        new TreeMap<>(new OperationResourceInfoComparator(m, "GET")).put(k, new Object());
    }
}
