Sun Completes Java Core Tech Open-Sourcing 141

Posted by Zonk from the the-beans-are-gratis dept.
MsManhattan writes "A year after announcing its plans, Sun Microsystems has made almost all of the core technology in Java available as open-source software under the GNU general public license version 2 (GPLv2).

    Rich Sands, community marketing manager for OpenJDK community at Sun, would not say what percentage of Java's 6.5 million lines of code are encumbered, but explained that it is largely Java 2D graphics technology, such as font and graphics rasterizing.

    In case anyone is wondering, this isn't much of a surprise to the Java community. When Sun was creating the latest and greatest Java libraries, they designed the APIs themselves to be generic. However, Sun generally licensed the underlying libraries for their reference implementation rather than developing them in-house. In the case of the Java2D APIs, they used code from Kodak to do all the fancy 2D rasterizations and transformations. This is why many Java coders thought that Sun's reference implementation would never be Open Sourced. (Happy to be wrong, BTW.)

    That code by itself could probably be replaced with a modern 2D rasterizer (similar to the types found in SVG and Canvas implementations), but it would need to be heavily overhauled to backport the VolatileImage support added in Java 1.4. (Basically, the JVM is able to manage the video card memory to store images for faster rendering and backbuffering.) I'm thinking that something OpenGL-based would be the best bet.

    However, that's not the only major library used. JavaSound also uses Dolby Headspace to render sound. It barely uses a fraction of the library's capabilities, but it would still need to be replaced. I don't know what was used for cryptography, but that would be replacable with a library like Bouncy Castle [bouncycastle.org].

    All in all, the final code shouldn't be too hard to replace as long as Open Source equivalents can be found. However, these areas *do* require significant expertise, so don't expect that joe random can jump in the code and make it happen.

        https://openjdk.dev.java.net/ [java.net]

        * Is there a list of the methods that need to be reimplemented?

        I imagine that the Graphics2D class as well as the VolatileImage class need to be implemented. The BufferedImage implementation may need to be modified to obtain the "Automatic Image" behavior seen in the Sun JVM. Depending on how much Sun has withheld, you may need to implement the GraphicsEnvironment code as well. I recommend asking on the mailing list for specifics.

        * Have I been tainted -- I've seen java code before, If I reimplement something and it might look like the previous code, how do I guard against this?

        The "tainting" problem was always an OSS community invention based on Sun's license wording. As long as the code you've seen is in the OpenJDK, it's quite impossible for you to be "tainted" as Sun has given it to you under the terms of the GPL. Of course, you should always consult a lawyer for the latest in paranoid-protective behavior, but I sincerely doubt that Sun would try and sue you over something they just gave you.

        * Can we make java better?

        You can do whatever the GPL license allows you to do. However, I imagine that OpenJDK won't accept anything more than implementation enhancements. New APIs need to go through the JCP for standardization before they can be accepted into a mainline JDK distribution. Again, ask on the mailing list for more details.

And this is a Good Thing (TM) Why is the banking industry so in love with Java? The bullet-proof JVM and portability of the languages. Not a single language before Java had ever offered such an incredibly good VM running on so many different hardware/software configurations.

Food for thought to anyone dismissing J2ME).

    Java is a success that has grown beyond anyone's wildest imagination and it just keeps getting better and better. I was an very early Java believer (back in the days where it was really messy to do Java development on Linux) and back in the days there were many misconceptions regarding Java. Nowadays it's simply unexcusable to try to deny that Java is a huge success. Like COBOL today, Java will still be the technology making the real-world work in decades (insert your lame jokes about COBOL here... I personally laugh everytime some COBOL is involved when you're making a real-world transaction [and, yup, I've done COBOL programming]).

    Note that (contrarily to C#/.Net) "Java the language" and "Java the VM" have been chosen because they were very impressive technologies, not because the company creating them had a monopoly on a certain market. C# is a copy (7 years later or so) of "Java the language", with some things done better (thankfully, 7 years later, that they got some things right ;) and some others done worse (*). This is a testimony to Java's quality as a third-generation OOPL (I'm not saying that third-generation language are the be-all end-all of programming nor that OO is the be-all end-all of programming, but simply that as an 3rd generation OOPL Java is very good).

    Thanks Sun.

    (*) C# has then been basically forced down the throats of programmers locked in the MS monopoly. If C# hadn't Microsoft's illegally maintained monopoly (the "illegally maintained monopoly" is a fact, checks your facts if you disagree) backing it wouldn't be anywhere near where it is today.

      As stated by James Gosling himself not long ago: it is basically impossible to do a financial transaction today without having Java involved at one point or another...

      No, I know at least one major bank where the retail banking system is written in Assembler. It just works and handles an incredibly large number of transactions. I know of exchanges where the backend is written in a mixture of C++/C & COBOL all the way through to the client APIs. You *can* use a Java based GUI on the system, but you coul

    • Very well written, and I personally agree with a lot of what you said.

      I also want to add a few more things which you have missed.

      Java is also part of the Blue-Ray Specification, with Java being used to create some of the more interactive Elements.

      Also here in Europe, Java is used in the MHEG DVB specifications, as well as new iterations of DAB.

      Recently, there has also been some work in creating emulators for other platforms using Java. However, they are not emulators, in the strict sense, as the native code
  • What about the poor folk like me running Linux on Sparc who can't use anything Java? Or some other architecture? Once this is complete it's going to be good for the non x86 Linux community.

      Finally, Java might be cross-platform after all!

      I use Kaffe (http://kaffe.org) on my Debian Sparc Linux system(s) with OK results. I use the version packaged for etch.

      Sure it has limitations:
      - it's not up to JDK 1.5+ levels for compatibility
      - performance *seems* slow but I haven't compared with Solaris+Sun-JDK on same hardware yet

      I wouldn't say "can't use anything Java" though.

      • On my Sun Blade 2000, Debian wasn't up to a version that had a compatible SILO apparently. Gentoo was the only one that worked. Haven't tried Debian 4 yet, which I presume works with a newer version of SILO now. Another issue was Flash. I wasn't aware of anything I could do about that. I was aware of an implementation like you had described, but was told it didn't really 'work.' Ah well I've decided to sell off my Sun Blade 2000, put it on craigslist. Too many bills and I need a good intel machine for play

          My systems are Ultra10s and a Netra T1 100. I've installed Debian sarge and etch on them. I mostly use them as server systems really so Flash and other desktop features are not so useful to me. Kaffe does have compatibility limitations but you can get it to work for a lot of applications. I was impressed that Tomcat and my webapps mostly work. I keep my needs modest at Java 1.4.x code and it largely works.

          The most annoying feature is I found Kaffe on sparc linux to be much slower than my sun jdk on int
          • That's funny because IME Sol 10 on the hardware you're mentioning crawls. I think it's more the JDK that's slow than the OS.

            You're not interested in a blade 2000 are ya? lol
