Integrating Guice with Jersey (squarespace): No ServiceLocatorGenerator installed

Question

I am deploying a Jersey 2.22 application which I am trying to integrate smoothly with Guice 4.0 using the Squarespace jersey2-guice-impl library so that I can easily inject Guice dependencies into my controllers.

(My apologies for minor typos below I have had to retype everything.)

But I get the following errors on startup, resulting from my WebListener:

   SEVERE: Exception starting filter jersey
   java.lang.IllegalStateException: It appears there is no ServiceLocatorGenerator installed.

I am using the following dependencies from my pom.xml:

 <dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guice</artifactId>
    <version>4.0.0</version>
 </dependency>
 <dependency>
    <groupId>com.google.inject.extensions</groupId>
    <artifactId>guice-servlet</artifactId>
    <version>4.0.0</version>
 </dependency>
 <dependency>
    <groupId>com.squarespace.jersey2-guice</groupId>
    <artifactId>jersey2-guice-impl</artifactId>
    <version>1.0.6</version>
 </dependency>
 <dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.22.2</version>
 </dependency>
 <dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.22.2</version>
 </dependency>
 <dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-multipart</artifactId>
    <version>2.22.2</version>
 </dependency>
 <dependency>
    <groupId>org.glassfish.jersey.ext</groupId>
    <artifactId>jersey-mvc</artifactId>
    <version>2.22.1</version>
 </dependency>

And this is the WebListener:

@WebListener
public class FakeResourceManager extends GuiceServletContextListener{
      @Override protected Injector getInjector(){
           return Guice.createInjector(new ArrayList<Module>());
      }
}

And this is web.xml

<filter>
     <filter-name>GuiceFilter</filter-name>
     <filter-class>com.google.inject.servlet.GuiceFilter</filter-class>
</filter>
<filter-mapping>
     <filter-name>GuiceFilter</filter-name>
     <url-pattern>/*</url-pattern>
</filter-mapping>
<filter>
     <filter-name>jersey</filter-name>
     <filter-class>org.glassfish.jersey.servlet.ServletContainer</filter-class>
     <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>mypackage.rest;guice.tomcat.jersey</param-value>
     </init-param>
     <init-param>
        <param-name>jersey.config.server.provider.classnames</param-name>
        <param-value>org.glassfish.jersey.media.multipart.MultiPartFeature;org.glassfish.jersey.server.mvc.jsp.JspMvcFeature</param-value>
     </init-param>
</filter>
<filter-mapping>
  <filter-name>jersey</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

I am deploying in Tomcat 7.0.42.

This seems very simple. I think there may be an ordering problem at load time. Perhaps the call to set the ServiceLocatorGenerator is not occurring before the filter loads. How do I force it to occur? What am I missing?
