The JAXRS mapping of Java methods without method parameter not working.
-----------------------------------------------------------------------

                 Key: CXF-1762
                 URL: https://issues.apache.org/jira/browse/CXF-1762
             Project: CXF
          Issue Type: Bug
          Components: Resources
    Affects Versions: 2.1.2
         Environment: Windows XP,
jdk 1.6.0_07

            Reporter: Frank Ittermann
            Priority: Minor


Hello everybody,

I implemented a REST resource that has a java method without method parameter.
@Path("/service")
@ConsumeMime({ "application/json;charset=UTF-8", "application/xml;charset=UTF-8" })
@ProduceMime({ "application/json;charset=UTF-8", "application/xml;charset=UTF-8" })
public class RestService {

    @GET
    @Path("/id/{id}")
    public SomeThingElse getSomeThingElse(@PathParam("id")int id) {
        return new SomeThingElse();
    }

    @GET
    public SomeThing getSomeThing() {
        return new SomeThing();
    }

}

If you call the rest uri /service the following error occur 
SCHWERWIEGEND: .No operation matching request path /adspaces/ is found, ContentT
ype : */*, Accept : text/xml,application/xml,application/xhtml+xml,text/html;q=0
.9,text/plain;q=0.8,image/png,*/*;q=0.5.

I changed the method getSomeThing and add a method parameter than it works.

any suggestions

And a other strange behavior is if you remove the method getSomeThingElse from the code than an error by creating the service occur. 
Here the error log:
