'Cannot find target method' when certain hex-encoded characters are used in 
@PathParam in GET requests
------------------------------------------------------------------------------------------------------

                 Key: CXF-3422
                 URL: https://issues.apache.org/jira/browse/CXF-3422
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS
    Affects Versions: 2.3.3, 2.3.1
         Environment: Tomcat 6
            Reporter: Karel Vlcek
            Priority: Minor


I have following simple JAX-RS service:

{code}
public interface RootService {
    @Path("data1")
    public DataService getDataService();
}

public interface DataService {
    @GET
    @Path("data2/{id}")
    public Data getData(@PathParam("id") String id);
}
{code}

All works correctly as long as URL contains in position of @PathParam("id") 
ASCII characters and digits or hex-encoded spaces. These URLs work:

GET /root/data1/data2/1
GET /root/data1/data2/AAA2BBB
GET /root/data1/data2/1%202

However, when URL on position of the parameter {id} contains certain 
hex-encoded characters other than space (1%202), like in this URL (this example 
contains digit '1' followed by 'latin capital letter d with caron'):

GET /root/data1/data2/1%C4%8E

I'll get following exception:
