The OpenJDK source code made available by Oracle America, Inc.
(Oracle) at openjdk.java.net ("OpenJDK Code") is distributed
under the terms of the GNU General Public License
<http://www.gnu.org/copyleft/gpl.html> version 2 only
("GPL2"), with the following clarification and special
exception.

Linking this OpenJDK Code statically or dynamically with
other code is making a combined work based on this
library. Thus, the terms and conditions of GPL2 cover the
whole combination.

As a special exception, Oracle gives you permission to
link this OpenJDK Code with certain code licensed by
Oracle as indicated at
http://openjdk.java.net/legal/exception-modules-2007-05-08.html
("Designated Exception Modules") to produce an
executable, regardless of the license terms of the
Designated Exception Modules, and to copy and distribute
the resulting executable under GPL2, provided that the
Designated Exception Modules continue to be governed by
the licenses under which they were offered by Oracle.

As such, it allows licensees and sublicensees of Oracle's GPL2
OpenJDK Code to build an executable that includes those
portions of necessary code that Oracle could not provide under
GPL2 (or that Oracle has provided under GPL2 with the Classpath
exception). If you modify or add to the OpenJDK code, that new
GPL2 code may still be combined with Designated Exception
Modules if the new code is made subject to this exception by
its copyright holder.
