Jersey-test-framework无用的回溯JerseyTest

Question

I have a test with an Error that gives no good information. The only piece of the stack that involves my code is the method call in the test which fails.

Test class:

package com.example;

import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.server.mvc.mustache.MustacheMvcFeature;
import org.glassfish.jersey.test.JerseyTest;
import org.junit.Test;

import javax.ws.rs.client.Invocation;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.Application;


public class FakeSiteminderServiceTest extends JerseyTest {

    @Override
    protected Application configure() {

        final ResourceConfig rc = new ResourceConfig().property(
                MustacheMvcFeature.TEMPLATE_BASE_PATH, "templates"
        ).register(
                MustacheMvcFeature.class
        ).packages("com.example");
        return rc;
    }

    @Test
    public void testGet() {
        System.out.println("111111111111111111111111111111111111");
        WebTarget t = target("/api/url");
        System.out.println(t.toString());
        Invocation.Builder b = t.request();
        System.out.println(b.toString());
        String respString = b.get(String.class); // <-- ERROR IS HERE
        System.out.println("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX");
        System.out.println(respString);
    }
}

The class I'm trying to test works fine when I run it with grizzly and render it manually with a browser.

@Path("url") public class FakeSiteminderService {

@GET
@Produces(MediaType.TEXT_HTML)
@Template(name = "/foo")
public Map<String, String> get(
        @Context HttpHeaders hh
) {
    Map<String, String> ctx = new HashMap<>();

    if (hh.getRequestHeader("FULLNAME") != null) {
        ctx.put("FULLNAME", hh.getRequestHeader("FULLNAME").get(0));
        ctx.put("EMAIL", hh.getRequestHeader("EMAIL").get(0));
    }
    return ctx;
}

You may be able to get some more information out or a different traceback if you put some code like this somewhere in your package:

@Provider
public class CustomExceptionMapper  implements
        ExceptionMapper<Throwable> {

    @Override
    public Response toResponse(Throwable ex) {
        System.out.println("EXCEPTIONMAPPER!!!!!!!!!!!!!!!!!!!!");
        System.out.println(Exceptions.getStackTraceAsString(ex)); // <--
        return Response.status(500).entity(
                Exceptions.getStackTraceAsString(ex)
        ).type("text/plain").build();
    }

}
