Introducing JITB — a Flash Player Built On the JVM 126

Posted by Soulskill from the stay-as-long-as-you-like dept.
MBCook writes "Joa Ebert has started working on a new program called JITB. Announced in a talk at FITC San Fran, it's a Flash player written to use the Java JVM to run ActionScript, and in a simple graphics test case (making 1 million calls to flash.geom.Point) was 30x faster than Adobe's Flash player. There is an impressive demo video on YouTube showing the point test."

      The problem here is not that the claim of a 30x performance increase was fallaciously generalized based on one particular piece of code as compared with Adobe's player, but that anyone familiar with Flash would find this claim to seem quite plausible.

      If someone claimed that they made a compiler that, say, generated code that was 30x faster than what Microsoft's compiler or gcc could do, no one would believe it for a minute.

      • But still many developers find these second-hand numbers appealing, despite being obviously bogus with even simplest of back-of-envelope calculations. It is very frustrating to see claims like "protobuf is 30 to 100 times faster than xml!" get repeated; same thing in this case. People tend to believe things they want to believe. "hey, flash is crap, of course it's easy to write something that's 10x faster", "Java is slow, my new programming language is 20x faster" etc. etc.. In many cases it is hard enough

        • Well, you'll never get rid of wishful thinking. Even a 10% speedup of some code takes weeks of programmer time, let alone 200% or 3000%. Yet hearing that a great speedup has taken place is always nice, even if only for a subset of an application.

    Adobe (back then Macromedia) used to ship Flash in two version: native binary and Java version in the days when Java applets were popular. They stopped developing it around the time Flash 4 was out, because the tables have turned: Java applets were going down, while Flash was going up.

    The article never mentions any reason as to why this player was developed, and I'm struggling to come up with a reason myself, as it's easier to port the native runtime to any platform, than maintain an independent copy in a constant "catch up" mode.

        The introduction of yet another semi-functional Flash alternative is doing nothing to change this position, as it's a practical position, not one of open source ideology. Having it in Java makes this even less interesting to Apple.

        Steve Jobs, like any other mobile maker, can have full access to the actual Flash player source code, if he only wanted it. Maintaining an independent port is not cheaper than simply fixing the one Adobe provides.

      The article never mentions any reason as to why this player was developed, and I'm struggling to come up with a reason myself

      I would think that the JVM itself is the main reason.
      Flash uses Actionscript, a variant of ECMAScript, just like Javascript.
      To run it fast enough, an implementation needs a fast and nice actionscript engine.
      One possibility would be to get a Javascript engine like Google's V8, Mozilla's Trace- / Jaegger-Monkey, Adobe's own opensourced Tamarin, etc.
      The other possibility is to use a well known and well optimised VM like Java and compile the Javascript into Java bytecode. This makes the process more complex, but leverages the years of JVM development.

      Also the second advantage is that lots of hardware contain already a functionning JVM : Lots of phone have Java EE, Android has the Java-like Dalvik (which can run java byte code after a transcoding), etc.

      as it's easier to port the native runtime to any platform

      Saddly, the main reference implementation of Flash is closed source (except for the Tamarin engine).
      So for a port you have 3 possibilities :
      - wait for Adobe to port the latest official player. Saddly they aren't doing it for lots of different architecture
      - port yourself one of the open source implementation (Gnash, LightSpark, Swfdec)
      - use a multi-platform player (Java)

    • as it's easier to port the native runtime to any platform

      Well, unless you have some chunks of code that are platform dependent. And I bet Flash has those pieces of code. Otherwise wou would have had Flash 64 bit without any issues, since you know, it would only require a recompile....

  • This sounds like a neat project... even without the speed improvements it would be nice to have a flash player that was portable and Free.

    That said, I can't wait to see the security holes of a Flash client combined with the security holes of a Java JVM! This is going to be AWESOME.

    This means very little. Anyone can make a subset of a language faster then a full implementation.

    The Ruby world has been through this recently: Someone comes out with a fantastic runtime that supports 1/8 of the ruby language, and it's 10x faster then everything else!

    There's lots of hype, but as development continues the other runtimes get 2x faster, and the new magic runtime gets 5x slower by actually supporting the whole language, and the new magic runtime is now the same speed as the rest of the field, with less compatibility and more memory usage.

    So color me skeptical, until this runtime supports the whole language, including transparent overlays and all the stuff that the Adobe guys claim makes Flash slow.

    Even the author of this article will tell you this. He recently added:

    Update: Please do not think that this implementation is 30x faster than the Flash Player developed by Adobe. One(!) microbenchmark is never a number you should count on. I would like to make clear that I never said this.

    That being said, If we're stuck with Flash for at least the near term, I'd like to see projects like this, Gordon [github.com], and Smokescreen [smokescreen.us] take off and perhaps improve our choices in runtimes. I just don't expect magic.
