HK2 failure has been detected in a code that does not run in an active Jersey Error scope

Question

Currently I am developing a jersey based RESTful application and would like to use DPI in my resources. (Note: Version of jersey is 2.23.1 and the servlet container is tomcat 8.5.3.)

Therefore I followed the tutorial Chapter 23. Custom Injection and Lifecycle Management in the jersey docs and created a resource, a factory and bind the factory to a class like this:

Resource:

@Path("/{project}/catalogs")
public class ProjectsResource {

   @Inject
   Project project;

   ...
}

Factory:

public class ProjectFactory extends Factory<Project> {

  private final Cache cache = cache.getInstance();

  @PathParam("project")
  private String project;

  private HttpServletRequest request;

  @Inject
  public ProjectFactory(HttpServletRequest request) {
    this.request = request;
  }

  @Override
  public Project provide() {
    return cache.get(project, Project.class);
  }

  @Override
  public void dispose(Project instance) {}

}

Also I have a feature, which registers an AbstractBinder, which binds my ProjectFactory to my Project class.

@Provider
public class ProjectFeature implements Feature {

  @Override
  public boolean configure(FeatureContext context) {

    context.register(new AbstractBinder() {
      @Override
      protected void configure() {
      bindFactory(ProjectFactory.class)
          .to(Project.class)
          .proxy(false)
          .proxyForSameScope(true)
          .in(RequestScoped.class);
    });

    return true;
  }

}

The actually problem is, when I call my Resource everything is fine and i can access my project instance, but in my tomcat catalina logs i am getting the following stacke trace:

Any ideas how I can solve this warnings?

Answer 1

I was able to solve this problem by using HK2's org.glassfish.hk2.api.PerLookup Annotation instead of Jerseys org.glassfish.jersey.process.internal.RequestScoped Annotation in my AbstractBinder class when I bind my factory to my interface.

import org.glassfish.hk2.api.PerLookup;

@Provider
public class ProjectFeature implements Feature {

  @Override
  public boolean configure(FeatureContext context) {

    context.register(new AbstractBinder() {
      @Override
      protected void configure() {
      bindFactory(ProjectFactory.class)
          .to(Project.class)
          .proxy(false)
          .proxyForSameScope(true)
          .in(PerLookup.class);
    });

    return true;
  }

}
