查了下wikipedia，似乎不算non-free，fsf认证

The Common Development and Distribution License (CDDL) is a free and open-source software license,[3] produced by Sun Microsystems, based on the Mozilla Public License (MPL). Files licensed under the CDDL can be combined with files licensed under other licenses, whether open source or proprietary.[2] In 2005 the Open Source Initiative approved the license. The Free Software Foundation (FSF) considers it a free software license, but one which is incompatible with the GNU General Public License (GPL).
