    Can you compile a FULLY functional JRE (not just rt.jar) and javac? If not, then this is no better than the MS source code access program. Look, but don't touch or try to do anything with it. Judging by the "SCSL Binaries - needed to complete source build", I'm guessing no.

          I was at a conference recently with some high level Sun employees, and this subject came up.

          Sun isn't ashamed to admit that Java is not open source, and likely won't be for the foreseeable future. In fact, they seem to get a little angry at the question pointing out that Sun has spent millions developing Java and now the community expects them to make it GPL or something. I'm not sure how keeping the development burden of Java internal to Sun really makes them money, though. Open sourcing would be the ultimate outsoursing... hundreds (or thousands) of developers all contributing to Java for free.

          The biggest argument against this I heard is that Sun would have to halt new features of Java for 9-12mos and concentrate on getting the source ready to be released. I don't get this at all... just throw it in CVS and do it with the help of the open source community.

          P.S. The Colorado Software Sumit is awesome!

          Miguel, you are wrong. The license says "You may use any information in intangible form that you remember after accessing the Technology, except when such use violates Sun's copyrights or patent rights." In other words, you can read the code to learn how it works and use that knowledge. You just can't cut-and-paste Sun's code into another project.

        And rightfully so. Don't forget Sun has invested a lot of both time and money into java. Frankly, I am surprised they go as far as they do now. From the license faq [java.net]:

        12. Am I required to keep my research "java compatible?"

        No. The license encourages you to innovate and experiment using the java technology core. It is expected that research implementations will not be compatible with the Reference Implementation from Sun. This is ok.

        13. Can I publish my source code at a conference, and in white papers?

        Yes, you may publish your work in the usually accepted academic manner as long as you reference the Java Research License and include the correct copyright information.

        14. Can I share my modifications with other researchers?

        Yes, provided that the other researchers have accepted the JRL.

        I might not be your regular open source hippy, but I feel that anyone that has taken the time to create software or whatever has the right to define the terms upon how it is used. Sure, the community has given a lot back. Some (can't find the link, but it was mentioned on slashdot some time ago) even argue that if it weren't for this Sun would be out of business by now. So it's a bit of giving and a bit of taking. This seems like a great gesture from Sun.

        • They've got the right to. And I've got the right not to use it. If they want me to use it, they have to design the license so that I find it useful to use.

        • but I feel that anyone that has taken the time to create software or whatever has the right to define the terms upon how it is used.

          Yes, and users have a right to discuss and decide for themselves whether a particular piece of software comes with a license that is acceptable. That's not "whining", it's sensible if you don't want to get locked into something proprietary. And it's something that both FOSS users and commercial users have a responsibility to do.

    Yes, you can download the J2SE 5.0 source code. But once you do, you will be bound by Sun's source code license agreements. Some companies and open source projects interpret those license agreements in such a way that you will not be able to work on projects covering anything that overlaps with functionality in the Java distribution.

    I'd recommend you read Sun's licenses carefully in their entirety and think about its implications carefully before you download the source code and look at it.

    Furthermore, you should carefully think about what you are getting out of agreeing to the license and what Sun is getting out of it (I find Sun's licenses inequitable).

        The GPL is a distribution license, not a use license. Firefox should still install even if you decline acceptance of the license. If it does not, it's a bug and should be fixed. A person can still redistribute Firefox and refuse to supply the source code, thereby violating the license, without ever installing it.
        • No, that's not how it works. A work is copyright by someone when they create it, whether or not it's registered with a copyright office. So that everyone can use it without infiging on their copyright, they license it for use. The license in this situation is the GPL. Now it's true that the details of the GPL cover distribution terms and not use terms. However, you must still accept their license to use the software. If you don't accept the license and continue to use it then you are infringing on the
          • No, you do NOT have to accept the GPL to merely use the software. By providing the software to you, the copyright holder is already allowing you to use it. The GPL even explicitly says that you needn't accept the license.

      • They were probably using some boilerplate installer that had a slot for licenseing terms, and they filled in with the GPL. Just a guess, I've seen it done before, though.

        It's a mistake, and the license doesn't require that you agree to it's terms before you install the software. (OTOH, it also doesn't make it legally required that you NOT have people agree to it before installing it.)

  • Listen, I'm not fully up to date about the arguments for why Java should be open source. If this isn't a GPL like license (is it?) then what good does it have being released? What are people expected to use this for? Will this mean Java is less secure? Are we going to start seeing java specific security issues? Why does anyone want the source code (besides the argument that if Sun went under a lot of applications would be out of support)?

      • Sun has this nasty habit of somehow getting themselves stuck in a rut with a particular major version number. For example, Solaris started on version 2.x and got all the way up to 2.6 something like 10 years later. With version 2.7, they kinda just said 'fuck it, marketing can call it Solaris 7', and they did. But to this day, "uname -a" on a Solaris 9 box says "SunOS turing 5.9 Generic_112233-05 sun4u sparc".

    Quoting Danese Cooper, Sun's open source diva:

    "IMHO (and IANAL) the JRL doesn't actually represent much of a change of terms from what the research and academic community could do under SCSL (there are some small changes around export), but it does clear away all the language in SCSL that is confusing, if you are only planning to engage in research."

    from http://today.java.net/pub/a/today/2003/06/24/jrl.h tml

    On a first look, there is not much difference between the JRL and the research provisions in the SCSL. The language got a bit clearer, and a few of the most hillarious provisions have been dropped.

    Research projects like JikesRVM, ORP, OVM and others seem to prefer to use GNU Classpath, rather than have their hands tied by proprietary, non-permissive licenses. I'd expect more research projects to join into the GNU Classpath pool, which is free software, in the future.

    It's definitely a step ahead for Sun. Good luck on the rest of the road to freedom without fear[1].

    I have yet to see a valid argument for why SUN doesnt release J2SE under an OSI complient licence.

    The argument that they want to be able to use the code in their own closed things, well they can do what OpenOffice.Org does and dual licence.

    There are clearly no arguments that can be made about "other peoples code", if there was anyone elses code in there, we wouldnt get to see it at all.

    As for the oft-pushed argument about forking, I said it before and I will say it again.
    What they need to do is to release the source code.
    Plus a testsuite.
    If you want to use the JAVA name on your particular binaries, those binaries must pass the testsuite.
    Releasing under a string copyleft like GPL that requires all source changes to be made public would also help stop forking because anything that is used can be added to the official sun tree.

    That way, anyone can use the source for whatever they like. But if you want to call something (be it modified from the SUN code or otherwise) JAVA, you have to pass the testsuite. That way, anything that has the JAVA logo on it (or whatever) is gauranteed not to be incompatible with SUNs VM.
    A good cpoyleft licence would also prevent what happened with Microsoft from happening again (since any additions could be added to the SUN VM)
