One possible explanation for the 20 second delay is that the curl call goes through a proxy (defined by the http_proxy/https_proxy environment properties), while Java does not pick up these properties. If this is indeed the case, you need to pass some system properties in your java call. See the documentation: https://docs.oracle.com/javase/8/docs/technotes/guides/net/proxies.html.
