Expanding a little on Alex's comment regarding the new HTTP Client.
I added the following comment as a suggestion to the online doc.

The new HTTP Client is being delivered in JDK 9 as an incubating
feature. It was previous proposed to be included in Java SE, but
later moved to incubating in JDK 9 b149. The link above to the
javadoc for HttpRequest clearly shows its previous package location.
This link is out of date. It is a bug in the documentation that this
link still works ( I’ll get that fixed ). JShell can be used with
the new HTTP Client as follows:
$ ./jdk-9_168/bin/java -version
java version "9-ea"
Java(TM) SE Runtime Environment (build 9-ea+168)
Java HotSpot(TM) Server VM (build 9-ea+168, mixed mode)
$ ./jdk-9_168/bin/jshell --add-modules jdk.incubator.httpclient
