Topic: OpenJDK is an open-source Java SE implementation to allow free development

[Software Santa]

OpenJDK is an open-source Java SE implementation to allow free COMMERCIAL development in the JAVA Environment.

Oracle's JAVA is a LICENSED and PROPRIETARY development platform that requires an expensive LICENSE: to allow you to do development for commercial products. Open JDK is an OPEN SOURCE and totally FREE version of Oracle's JAVA Development Kit (JDK for Short) that you can use for any purpose. ALL Java developers should switch to OpenJDK ASAP ... and Stop paying License Fees to Oracle!!

Open Source, Open Innovation, Open Standards

What is this? The place to collaborate on an open-source implementation of the Java Platform, Standard Edition, and related projects.

What are Oracle's plans to support open innovation in Java?
We intend to to continue to support open-source and open standards. Oracle is committed to offering choice, flexibility, and lower cost of computing for end users, and we cannot stress enough the importance of using open standards, whether in the context of open-source or non-open-source software.

Does Oracle practice open-source development?
Oracle is leading or involved in a large number of open-source projects. Please see http://oss.oracle.com for a list of open-source and for more information about open-source at Oracle.

Can I learn more about Oracle's view on open-source and open standards?
Sure. See http://www.oracle.com/technetwork/oramag/2010/o40interview-086226.html for an interview with Oracle Chief Corporate Architect Edward Screven on the importance of open source and open standards.



Oracle's plans for OpenJDK

What are Oracle's plans for the OpenJDK Community?

Oracle plans to continue to work on the next release of the Java SE platform with the Java community as part of the OpenJDK project. OpenJDK is the only open-source Java SE implementation to which Oracle plans to contribute.

Is Oracle committed to OpenJDK?
Yes. Oracle remains committed to OpenJDK as the best open-source Java implementation and we will continue to improve OpenJDK and welcome external contributors.

Could you elaborate some more on Oracle's plans for OpenJDK?
Of course. The roadmap announced at JavaOne 2010 for Java SE accelerates the availability of Java SE with two releases, one in 2011 and one in 2012. The corresponding OpenJDK releases will continue to serve as the basis for the Oracle Java Development Kit (JDK) 7 and JDK 8. You can find out more about the roadmap and Oracle's plans at http://blogs.oracle.com/henrik/2010/10/java_roadmap_from_javaone_2010.html.


What is JDK 13?
JDK 13 is the name of Oracle's implementation of the next version of the Java SE platform. The JDK 13 Project in the OpenJDK open-source Community is the where Oracle, in concert with the broader Java and open-source community is working on implementing the features to be specified in the recently-approved Java SE 13.

Will Oracle change the OpenJDK licensing model?
No. The OpenJDK Community continues to thrive with contributions from Oracle, as well as other companies, researchers, and individuals, and the GPL-based licensing model is one large part of this success. Oracle has no plans to change it.

I heard that IBM is joining OpenJDK?
Yes. Oracle and IBM announced in October 2010 that we will collaborate in the OpenJDK Community to develop the leading open-source Java SE implementation, and make the OpenJDK Community the primary location for open-source Java SE development. Oracle and IBM will support the OpenJDK development roadmap that was proposed before JavaOne 2010, which accelerates the availability of Java SE across the open-source community. The collaboration between Oracle and IBM builds on the success of OpenJDK as the primary development platform for Java SE, and of Oracle's and IBM's long history of contributions to the Java community.

OpenJDK Users & Contributors
Who uses OpenJDK?
Major Linux distributions such as Ubuntu, Fedora or Red Hat Enterprise Linux offer OpenJDK as their default Java SE implementation. In addition, the Eclipse Community Survey 2010 found that while most Java developers use Oracle's commercial JDK releases, 21% of the developers participating in the survey used OpenJDK. Last but not least, many academic institutions publish research referencing or based on OpenJDK.

Who contributes to OpenJDK?
Most OpenJDK contributors are engineers employed by companies like Oracle to work on OpenJDK. In addition, the OpenJDK Community has a strong showing of academics, open-source operating system distribution developers, and individual software developers with an itch to scratch. Oracle has no plans to change the contribution model and is gladly accepting new contributors. In order to learn how to contribute to OpenJDK, please see http://openjdk.java.net/contribute/.

Why is Oracle participating in OpenJDK ?
Oracle is committed to developing the JDK codebase using an open-source model. Oracle is committed to this way of working because it allows the best ideas for evolving the technology to be shaped and brought into the codebase by lowering the barriers to participation.
