Jersey returns HTTP Status 405 - Method Not Allowed
===

I have a very simple endpoint using Jersey. My URL is static, it doesn't require any request parameters. It looks like this: 

    @GET
    @Path("/chart")
    @Produces(javax.ws.rs.core.MediaType.APPLICATION_JSON)	
    public String getData()  {
      return "{'name': 'value'}";
    }

However, whenever I request this URL, I always receive a HTTP Status code of 405 - Method Not Allowed.

The weird thing is, that if I change the @Path annotation and define a path variable e.g. @Path("/chart/{blah}") it works fine.

Does anyone have an idea why I have to define a path variable to get this to work? I don't need a path variable and it seems silly to add one just to get a 200 response.
