title: Jersey @NotNull validation not working
body: <p>I want to use the Jersey bean validation, so here 's the code for that,</p>
  
  <p>Jersey version is : 1.17.1 for me</p>
  
  <p>Here is the Maven Dependency I am using, given <a href="https://jersey.java.net/documentation/latest/bean-validation.html" rel="nofollow">here</a></p>
  
  <p>Also the code I am using is:</p>
  
  <pre><code>@POST
  @Path("abc")
  @Consumes(MediaType.APPLICATION_JSON)
  @Produces(MediaType.APPLICATION_JSON)
  public Response postAbc(@NotNull @HeaderParam(value="AccessId") String accessId){
    ////
  }
  </code></pre>
  
  <p>Now my question is when I don't pass the HeaderParam of AccessId, even then it is not showing any exception or so, so my question is should I missed anything?</p>
