Subject: Preview builds of Jigsaw available

We now have a download page on to host preview builds from Oracle:­

This should be useful to those that want to try out Project Jigsaw
and/or the current prototype of the modular JDK without needing to
build it themselves.

The preview builds come in two forms:

- "JDK modules image". This is essentially equivalent to the normal
JDK download except that everything is pre-installed as modules.

- The other download choice is for those that wish to experiment with
a ready-to-assemble JDK. The download contains an image that is a base
runtime and also contains a directory of jmod packages that are the
JDK modules. These modules can be installed with the included jmod
tool as needed.

At this time there isn't a download for Mac OS X, that should come
soon (a small issue meant it didn't make the initial push). Another
issue is that the Solaris downloads are the 32-bit binaries only for

As these are preview builds they will of course be issues and bugs.
The main issue that people will likely run into is that crypto is
currently disabled. There are also several areas in the JDK that
require API and implementation changes to work as modules and that
will come in time.

Thanks to Roger Yeung, David Katleman, Christine Lu from the Release
Engineering team in Oracle for making these builds available. At this
time we haven't decided how often to update the bundles so it will
likely be "as needed" for now.
