CDDL is a file based license, so they use the files and follow the license on those files, which grants them rights to use it. The GPL/CDDL license wars over DTrace went on for years. It was a real shame -- we should have been discussing or using a great technology instead. There must be a hundred different ways and languages we can try, some of them may be better than DTrace's D. One of them is Oracle copyrighted, and lacks some features we need (stack saving). I'd either A) talk to a lawyer, or B) pick one of the other 99 options.
