java - Jersey : HttpServletRequest is coming as Proxy while using @context

Question

I have a jersey rest controller called Test.

@Path("/listusers")
public class Test {
    @Context 
    private HttpServletRequest request;
        @GET
    public void listUser(){
        System.out.println("testing...");
            //getting parameters from the request and doing something
    }
}

When I run the code, I am getting error saying that

No thread local value in scope for proxy of class com.sun.proxy.$Proxy18

I am not able to understand the reason for this. I have some other classes where I am using similar url, without any problem.

I tried googling, but was not able to find any solution.

My web.xml entry is

<servlet>
      <servlet-name>rest-controller</servlet-name>
      <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
      <init-param>
       <param-name>jersey.config.server.provider.packages</param-name>
       <param-value>com.mypackage</param-value>
      </init-param>
      <load-on-startup>1</load-on-startup>
   </servlet>

<servlet-mapping>
        <servlet-name>rest-controller</servlet-name>
        <url-pattern>/listusers</url-pattern>
    </servlet-mapping>

Can someone help me with this?
