Where to download JMXMP?
===

I want to profile a Java application with VisualVM, remotely via JMX. Because it's a NAT'ted and firewalled EC2 instance, I can't use the default RMI approach and need to use the optional JMXMP extensions, which I must first download.

> NOTE – IF YOU WANT TO USE A JMXMP CONNECTOR, DOWNLOAD THE JSR 160
> REFERENCE IMPLEMENTATION FROM
> HTTP://JAVA.SUN.COM/PRODUCTS/JAVAMANAGEMENT/DOWNLOAD.HTML, AND ADD THE
> JMXREMOTE_OPTIONAL.JAR FILE TO YOUR CLASSPATH. YOU WILL FIND EXAMPLES
> OF USE OF THE JMXMP CONNECTORS IN THE JMX REMOTE API TUTORIAL INCLUDED
> WITH THE JSR 160 REFERENCE IMPLEMENTATION.

http://docs.oracle.com/javase/6/docs/technotes/guides/jmx/overview/connectors.html

But when I go to that page, I cannot find the download. In fact, Google cannot find the download. Where can I get these extensions?
