What happens when there is duplicate path param?

Imagining that I have some endpoint defined as:

@Path("path/{variable}/{variable})
class Resource {
    @Path("hey")
    public void function(@PathParam("variable") variable) {

    }
}

In the case of calling path/A/B/hey what will be the value bound to variable?

I'm aware I could use UriInfo#getPathParameters() but I'd like to know what's the specified behaviour in this case.
