Subject Moving Java Forward Faster
Date Thu, 07 Sep 2017 09:12:45 GMT
Hi Mark & Gavin,

Oracle is proposing a rapid release model for Java SE going-forward.

The high points are highlighted below, details of the changes can be 
found on Mark Reinhold’s blog [1] , OpenJDK discussion email list [2].

Under the proposed release model, after JDK 9, we will adopt a strict, 
time-based model with a new major release every six months, update 
releases every quarter, and a long-term support release every three years.

The new JDK Project will run a bit differently than the past "JDK $N" 
Projects:

- The main development line will always be open but fixes, enhancements, 
and features will be merged only when they're nearly finished. The main 
line will be Feature Complete [3] at all times.

- We'll continue to use the JEP Process [4] for new features and other 
significant changes. The bar to target a JEP to a specific release will, 
however, be higher since the work must be Feature Complete in order to 
go in. Owners of large or risky features will be strongly encouraged to 
split such features up into smaller and safer parts, to integrate 
earlier in the release cycle, and to publish separate lines of 
early-access builds prior to integration.

The JDK Updates Project will run in much the same way as the past "JDK 
$N" Updates Projects, though update releases will be strictly limited to 
fixes of security issues, regressions, and bugs in newer features.

Related to this proposal, we intend to make a few changes in what we do:

- Starting with JDK 9 we'll ship OpenJDK builds under the GPL [5], to 
make it easier for developers to deploy Java applications to cloud 
environments. We'll initially publish OpenJDK builds for Linux/x64, 
followed later by builds for macOS/x64 and Windows/x64.

- We'll continue to ship proprietary "Oracle JDK" builds, which include 
"commercial features" [6] such as Java Flight Recorder and Mission 
Control [7], under a click-through binary-code license [8]. Oracle will 
continue to offer paid support for these builds.

- After JDK 9 we'll open-source the commercial features in order to make 
the OpenJDK builds more attractive to developers and to reduce the 
differences between those builds and the Oracle JDK. This will take some 
time, but the ultimate goal is to make OpenJDK and Oracle JDK builds 
completely interchangeable.

- Finally, for the long term we'll work with other OpenJDK contributors 
to establish an open build-and-test infrastructure. This will make it 
easier to publish early-access builds for features in development, and 
eventually make it possible for the OpenJDK Community itself to publish 
authoritative builds of the JDK.
