JDK 9 Early Access with Project Jigsaw build b36 is available on
The goal of Project Jigsaw  is to design and implement a standard
module system for the Java SE Platform,
and to apply that system to the Platform itself and to the JDK.
As described in JEP 220 , this build provides a new runtime image
structure. For example, this new runtime
image does not install an rt.jar file or a tools.jar file.
