Thank you for downloading this release of the Java TM Platform, Standard Edition Development Kit (JDK TM).The JDK is a development environment for building applications, applets, and components using the Java programming language. Java for macOS 2017-001 installs the legacy Java 6 runtime for macOS 10.13 High Sierra, macOS 10.12 Sierra, macOS 10.11 El Capitan, macOS 10.10 Yosemite, macOS 10.9 Mavericks, macOS 10.8 Mountain Lion, and macOS 10.7 Lion.
Java SE 6/SE 7 Runtime is installed on the computer.

Note:
In Dreamweaver 2014, the prompt does not appear when you launch Dreamweaver. However, you are prompted to install Java SE 6 runtime while logging in to PhoneGap Build service (Site > PhoneGap Build Service > PhoneGap Build Service).
In the pop-up window that appears, click Install and follow the onscreen instructions to install Java SE 6 Runtime.
Note:
In Dreamweaver 2014, you can't log in to PhoneGap Build service without installing Java SE 6 Runtime.
Important: Ensure that you install Java SE 6 Runtime only by clicking Install in the pop-up window. If you install Java SE 6 or 7 Runtime through any other means (for example, by directly accessing Java.com), Dreamweaver could still display the prompt.
Even if you have installed Java SE 7 Runtime, you still need to install Java SE 6 Runtime as described above.
If you continue to see the prompt even after installing Java SE 6 Runtime as described above, perform the following steps:
Dreamweaver displays such a prompt because, when you update to Mac OS 10.9, Java SE 6 Runtime on your computer gets uninstalled.
I've just installed Mac OSX 10.8 Mountain LionI'm trying to install a JDK version 6There's no Mac package for version 6 on the Oracle downloads:http://www.oracle.com/technetwork/java/javase/downloads/jdk6u37-downloads-1859587.html
But there is one for JDK version 7http://www.oracle.com/technetwork/java/javase/downloads/jdk7u9-downloads-1859576.html
Is there somewhere else I can get a Mac package for JDK 6?
As I recall, the first time you do something that needs Java the OS will ask if you want to install it, and version 6 is what you get. According to this page, typing java -version in the Terminal is enough to trigger the prompt.
For the JDK (and not the runtime), you'll need to log into developer.apple.com, search for java, and download the Java for OS X 2012-006 Developer Package. I just did this on my MacBook and now have javac 1.6.0_37.
