    BZZT! WRONG! Java source code has been available for YEARS! (And no, I'm not going to bother linking. If you don't already know where to find the SCSL and JRL licensed code by now, you need to pull your head out of your butt and Google it.)

      Unfortunately, one of OSI's core requirements is forking. So Java will never be able to make the pundits happy.

      Sure they can - there are other ways to pevent forking than in the license. Look at most of the major OSS projects around and you'll see that there is very little in the way of forking - sure minor forks exist but they quickly die. Sun doesn't care about some minor fork of Java that 20 people use that eventually dies, they are worried about a significant competing standard that honestly splits developers between two different platforms. How often has that happened with big OSS projects? Hardly ever. The question is not so much "what can be done to prevent forking" but "what happens that causes a successful fork". The major examples of significant splits in the OSS world would be Emacs/XEmacs, gcc/ecgs, and XFree86/Xorg. In each of those cases the reason for both the fork, and the success of the fork, comes down to the original project stagnating and being unresponsive to change. Avoid that and you tend to avoid significant forks.

      • Remember the Unix wars [wikipedia.org] fiasco?
        • Which interestingly enough took place between proprietary systems, not open ones. In that sense the UNIX wars are more akin to the battle between Java and C# and .NET (which could, indeed, be seen as damaging to the VM market). That is to say, regardless of what Sun does with Java they are already facing the same sorts of problems.

        But they DO care about IBM or Microsoft creating a VM that advertises compatbility, but actually pulls the bait-and-switch routine. Remember, Microsoft already tried to pull that routine with the NON-OSS version of Java. It was the license that stopped them. This time, you can be sure that they would stay precisely inside the letter of the law. No Java trademarking, but no compatability testing either. Companies will start to rely on it for its Windows performance, and then Microsoft will start introducing subtle differences. Before you know it, users will blame Sun for being incompatible.

            Microsoft's probable response to OSS Java, would be to comb through the source code for bugs, and call a press conference to announce "one gadzillion bugs found in open source Java, more probably exist".

          You throw out a couple of scare scenarios here with either Microsoft or IBM making a mess of Java, but as far as I can tell they are just that, wild scare scenarios that simply aren't viable if Sun is at all on the ball. For starters Sun can keep the Java trademark and simply bar Microsoft and IBM from advertising whatever they care to sell as "Java". From there it is a question of exactly how either Microsoft or IBM is going to get their new language and VM (whatever they decide to call it - maybe microsoft will call it C# and .NET; no, wait, they already did that) to be dominant, or at least bootstrap it into being a competing standard. Microsoft can do that, as you point out, by leveraging their monopoly. The thing is they've already done that: C# and .NET. They can do that quite successfully whether Sun opens sources Java or not. So for Microsoft the argument is rather moot. What about IBM? They don't have a monopoly to leverage so they'd have to resort to the nasty tactic of making a better language and VM with better libraries to manage to get it to take off. But wait, they can only do that if Sun drop the ball in exactly the manner I described and let Java stagnate and become unresponsive to change. So we're back where we started. Sun open sourcing Java really isn't going to make a lot of difference unless Sun drops the ball themselves - which is exactly what I originally said.

          • If Sun can stop anyone from using the word "Java" then we agree, but if they allow forks then it appears that Microsoft could call it MsJava and change their vm to also accept Java compiled code.

    • Unfortunately, one of OSI's core requirements is forking.

      There are ways to minimize forking. For example, a license could require modifications be distinct from the original (ei. patching). The QPL license does this. But a far easier way is to simply trademark the name (already done), and only permit it to be used on the original (or approved) code bases.

    Anyone can use the code. You can only call yourself "Java" if you hit certain specs and pass some tests. In other words, if you can prove that you meet the Java standards (with API support etc), you can call yourself Java and use the source code. If not, you aren't Java. Feel free to use the source code.

If anything, McNealy was just an arrogant ass who liked staying in his ivory tower with Bill Gates and Larry Ellison. Schwartz has always shown to be more of a geek than McNealy, and releasing the source code to Java has been a "cry of the geeks" for a long time.

    i think this is a great idea. one of my biggest annoyances with writing java apps has been that if i ever wanted to release my programs and didn't want to make any assumptions about my users (mainly that they had any version of java already installed on their system let a lone a level of java that matched my own level) i would have to deploy a very heavy 50MB JRE with my 100K app... i think with the opening of the java source, much like in the linux world, someone will repackage the JRE and just keep the very bare-bones essentials so that instead of deploying a 50MB+100K apps i can deploy a 5MB+100k app.

The program isn't debugged until the last user is dead.
