Sun Releases New License for Java Compatibility Tests to the OpenJDK Community

Aug 09, 2007, 01:00 ET from Sun Microsystems, Inc.

    SANTA CLARA, Calif., Aug. 9 /PRNewswire-FirstCall/ -- Sun Microsystems,
 Inc. (Nasdaq:   SUNW), today announced the immediate availability of the
 OpenJDK(TM) Community Technology Compatibility Kit (TCK) License. With this
 release, Sun is placing the means for certifying "Write Once, Run
 Anywhere(TM)" compatibility into the hands of the community.
     This license is for the Java(TM) Compatibility Kit (JCK). The JCK is
 the Technology Compatibility Kit, a suite of tests, tools and documentation
 that determines whether or not an implementation complies with the Java
 Platform Standard Edition 6 specification. The evolving OpenJDK community
 understands that the value of their efforts, as well as the resulting open
 source Java technology implementations, will be greatly enhanced if these
 implementations can be certified as compatible.
     Sun is licensing the JCK under terms that will permit contributors to
 fully comply with the terms of the GNU General Public License version 2
 (GPLv2), while giving the OpenJDK community the means to test for
 compatibility. The OpenJDK Community TCK License is available at:
     "This announcement is another milestone in the release of Java
 technology as open source software. We're eager to see OpenJDK based
 implementations pass the JCK, so that we have compatible and free Java
 technology implementations available in GNU/Linux distributions
 everywhere," said Rich Green, executive vice president, Software at Sun.
 "As a result of this new license and the efforts of the OpenJDK community,
 we will see the promise of open source Java technology fulfilled through
 accelerated innovation and broader distribution, which will benefit the
 entire IT industry."
     The OpenJDK Community TCK License will enable developers to test the
 compatibility of their contributions to the OpenJDK project. It will also
 allow distributors to test complete implementations that are substantially
 derived from OpenJDK and distributed under GPLv2. Organizations or
 individual developers that use the OpenJDK Community TCK License and then
 successfully pass compatibility testing, will also have the option of
 branding their implementation with Sun's "Java Compatible" trademark and
