It's not even Creative Commons, it's CC-zero, which is public domain or as close as it gets. Strangely, the file that you linked has a GPL overlay: /* * This file is available under and governed by the GNU General Public * License version 2 only, as published by the Free Software Foundation. * However, the following notice accompanied the original version of this * file: * * Written by Doug Lea with assistance from members of JCP JSR-166 * Expert Group and released to the public domain, as explained at * http://creativecommons.org/publicdomain/zero/1.0/ */ https://github.com/netroby/jdk9-dev/blob/master/jdk/src/java... I wonder where the original CC-zero version is located.
