> It is open source, but I wouldn't exactly call it free as in freedom due to GPL-incompatibility The CDDL is essentially the same license as the GPL except it only applies to the files under the CDDL as opposed to the GPL which imposes its rules to the entire project for every project that links it. Any software under the CDDL is exactly as free as in freedom as GPL code.
