Sun Open Sources Java Under GPL
prostoalex writes "The embargo is off, and Associated Press is reporting on Sun releasing Java under GPL. Sun is hoping that this step will attract more developers, as well as extend the lifespan of Java. The article notes that this is 'one of the largest additions of computer code to the open-source community', and that Java is currently being run on something like 3.8 Billion devices worldwide." From the article: "Rich Green, Sun's executive vice president of software, said the company hopes to turn more developers into Java programmers, who may then create additional software to support Sun products. 'The open-sourcing of this really means more — more richness of offerings, more capability, more applications that consumers will get to use,' Green said. 'The platform itself will become a place for innovation.' All the Java source code is expected to be released by March 2007, Green said. The move covers all Java technology, which includes software that runs on handheld devices, personal computers and servers."
I don't think the Mono folks are rejoicing ;)
With this step, SUN has became the largest commercial contributor to the free and open source software pool. OpenOffice.org, OpenSolaris, now JAVA - well, kudos!
Why the heck didn't Sun do this 10 years ago? It would have save the world a LOT of grief.
Because 10 years ago, before Java had built up the momentum it has today, a certain company deliberately embraced, extended and corrupted the core libraries with their own OS specific extensions, and shipped this version with their operating system until they were forced by court to stop. Had they succeeded Sun would have lost control of the language to the other company, or it would have been forked to irrelevance. This understandably made Sun a bit paranoid about having total control over Java for quite a while.
Being bitter is drinking poison and hoping someone else will die
I think you misunderstood what I wrote. There are no patent problems with java, simply because SUN chose to license it under the GPL. Java is copyrighted by SUN, and it has a large IP portfolio over java technologies (lots of patents). As soon as they switched over to GPL, they immediately granted free use of these patents to every programmer who builds on java and distributes his code under the GPL. With SUN's choice, there are no longer any patent issues with java. Now contrast this with the deal Novell stuck with Microsoft, that guarantees a 5 year revocable (!) protective covenant for novell customers (and novell customers alone, according to SteveB himself) alone. The difference is HUGE! Of course, the details of the deal are not known - there may or may not be MS IP in Mono. Saying that there are is simply FUD, but than, Microsoft and Novell agreed not to sue each other's customers for patent infringement... which reinforces the perception that there might be patents. And which is the most likely candidate from the software stack distributed by Novell? The Linux kernel? KDE? Apart from perhaps Samba, Mono is the most likely candidate for patent infringement ... I think that is why Perens warns against it. But still, I must emphasize, that this is just my speculation. Don't take it too seriously (my original post was sarcastic, but ./ removed the evil-comment tags). One thing is certain: since SUN decided to distribute java under the GPL, as far as patents goes, it become safe. This cannot be said of Mono, even though you cannot claim the opposite either with absolute certainty... You see what meant now?
