HttpClientBuilder placing last HttpRequestInterceptor first

CloseableHttpClient client = HttpClients.custom()
    .addRequestInterceptorFirst((request, entity, context) -> {
        System.out.println("This should be first");
    })
    .addRequestInterceptorLast((request, entity, context) -> {
        System.out.println("This should be last");
    })
    .build();

client.execute(new HttpGet("http://www.example.com"));

This should be last
This should be first

if (entry.postion == RequestInterceptorEntry.Postion.LAST) {
    b.addFirst(entry.interceptor);
}

if (entry.postion == RequestInterceptorEntry.Postion.LAST) {
    b.addLast(entry.interceptor); 
}
