Hi Guillaume,
The initial changesets for JEP 220: Modular Run-Time Images [1] are
available
with JDK 9 early-access build 41 [2].
To summarize (please see the JEP for details):
- The "jre" subdirectory is no longer present in JDK images.
- The user-editable configuration files in the "lib" subdirectory
have been moved to the new "conf" directory.
- The endorsed-standards override mechanism has been removed.
- The extension mechanism has been removed.
- rt.jar, tools.jar, and dt.jar have been removed.
- A new URI scheme for naming stored modules, classes, and resources
has been defined.
- For tools that previously accessed rt.jar directly, a built-in NIO
file-system provider has been defined to provide access to the
class
and resource files within a run-time image.
More details are available at Mark Reinhold's latest blog entry [3]
Rgds, Rory
