OPENJDK ASSEMBLY EXCEPTION

The OpenJDK source code made available by Sun at openjdk.java.net and
openjdk.dev.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, Sun gives you permission to link this
    OpenJDK Code with certain code licensed by Sun 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 Sun.

As such, it allows licensees and sublicensees of Sun's GPL2 OpenJDK Code to
build an executable that includes those portions of necessary code that Sun
could not provide under GPL2 (or that Sun 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.
