I mention it because that was Transvirtual's old position. Yes, I believe it to be FUD too. :-) I'm just trying to lay out the situation and the history so that people can make an intelligent decision themselves as to whether or not there is a legal risk for them. I would love to be able to say there is "no risk" that somebody using Kaffe would ever be sued, but I'm not a lawyer (and I doubt you could ever get a lawyer to say that either). Remember, companies like SCO will sue people even if they have no legal basis for a case. I didn't even mention the messy situation with software patents, particularly in the U.S., and possibly Europe, soon... Who knows what patents companies like Sun, IBM, Microsoft and others are holding that might apply to our implementation? > GNU explicitly says that is not the case, and if > it were the case then any non-open source application running on Linux > would be in violation. True, and the Linux license also adds a "clarification" to make that very clear. > http://www.gnu.org/licenses/gpl-faq.html#PortProgramToGL > > The lack of undue dependency for VM's made clear here: > > http://www.gnu.org/licenses/gpl-faq.html#InterpreterIncompat > > The poster's original question is also answered by GNU: > > http://www.gnu.org/licenses/gpl-faq.html#TheGPLSaysModifiedVersions The same page also says that subclassing a GPL'd java class is creating a derivative work. Kaffe's class libraries were GPL'd. We've almost completely moved over to using the Classpath projects class libraries, which are GPL+Exception, so hopefully that will provide some more license "insulation". :-) Cheers, - Jim _______________________________________________ kaffe mailing list kaffe@kaffe.org http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
