There is a huge problem in that the CDDL is "viral." It "infects"
products with which it is combined. You can read the text of the
CDDL at

http://www.opensource.org/licenses/cddl1.php

Section 3.1 of the CDDL is the portion which is essentially equivalent
to the GPL. 

This is part of the nastiness of viral licenses.
