Description

I have following simple JAX-RS service:

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

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

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 (%20), 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:
