Для org.glassfish.jersey.process.internal.RequestScoped существует несколько активных контекстов.

У меня возникают трудности с извлечением объекта RequestScoped внутри ContainerRequestFilter, что я пытаюсь сделать, введя Provider в свой фильтр.Моя конфигурация приложения выглядит следующим образом: 

class MyResourceConfig extends ResourceConfig
{
  public static class MyBinder extends AbstractBinder 
  {
    @Override
    protected void configure()
    {
      bindFactory(PolicyFactory.class)
        .to(Policy.class)
        .in(RequestScoped.class);
    }
  }

  public MyResourceConfig()
  {
    register(new MyBinder());
    register(MyDynamicFeature.class);
  }
}

@Provider
class MyDynamicFeature implements DynamicFeature
{
  @Override
  public void configure(ResourceInfo ri, FeatureContext ctx)
  {
    ctx.register(MyRequestFilter.class);
  }
}

@Priority(Priorities.AUTHENTICATION)
public class MyRequestFilter implements ContainerRequestFilter
{
  @Context
  private HttpServletRequest request;

  @Context
  private ResourceInfo resourceInfo;

  @Inject
  private javax.inject.Provider<Policy> policyProvider;

  @Override
  public void filter(ContainerRequestContext requestContext) throws IOException
  {
    policyProvider.get();
  }
}

Когда провайдер вызывается в MyRequestFilter, я получаю следующее исключение: 

A MultiException has 2 exceptions.  They are:

В этом конкретном случае я выполнял вызов из модульного теста с Grizzly, настроенным для развертывания сервлета.Эта проблема также возникает, когда не используется развертывание сервлета, а также при реальном запуске приложения (Tomcat).

Как решить эту проблему?

Проблема связана с более новыми версиями Джерси.Следующий MCVE не работает с Джерси 2.27 или 2.26, но передает 2.25:

build.gradle 

apply plugin: 'java'
apply plugin: 'eclipse-wtp'

repositories {
   mavenCentral()
}

sourceSets {
  src {
    java {
      srcDirs = ["src/main/java"];
    }
  }
  test {
    java {
      srcDirs = ["test/main/java"];
    }
  }
}

def jerseyVersion = '2.25'

dependencies {
  compile "org.glassfish.jersey.containers:jersey-container-servlet:${jerseyVersion}"
  compile "org.glassfish.jersey.inject:jersey-hk2:${jerseyVersion}"
  testCompile "org.junit.jupiter:junit-jupiter-api:5.2.0"

  testCompile "org.glassfish.jersey.test-framework:jersey-test-framework-core:${jerseyVersion}"
  testCompile "org.glassfish.jersey.test-framework.providers:jersey-test-framework-provider-grizzly2:${jerseyVersion}"
