> I suggest you ask a lawyer. Thanks for the suggestion but individuals like me don't have lawyers available so easily, especially those involved in licences issues :)
Usually there is people very aware of licences problematics in OSS community, that's why I'm trying to get answers here :) In IcedTea FAQ (http://icedtea.classpath.org/wiki/FrequentlyAskedQuestions) "What license is IcedTea released under? IcedTea is released under the GPL2 + Classpath exception, which is the same license as both GNU Classpath and OpenJDK. " IcedTea include Rhino, so I guess GPL2 + Classpath may be a valid licence. If IcedTea guys are around, advices more than welcomed
