When injecting an UriInfo reference into a field in a Stateless Session Bean, the getQueryParameters() methods always returns the parameters for the first request.

For example the following code:

@Path("/resource")
@Stateless
public class MyResource {
  @Context
  private UriInfo uriInfo;

  @GET
  public String get() {
    return ""+uriInfo.getQueryParameters().get("param");
  }
}

/resource?param=8 returns [8], after that, /resource?param=42 also returns [8].
