Issue when injecting @QueryParam values when the URL query string has percentage encoded &

Issue

I have a resource like:

@GET 
@Path("/foobar")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Response get(@QueryParam("x") String x, @QueryParam("y") String y, @QueryParam("z") String z) {
}

If I call this resource with /foobar?x=a%26y=b%26z=c then x get assigned with the value a%26y=b%26z=c and y and z are set to null.
