To Avoid Confusion: Oracle's Confusing New Java Numbering Scheme 183

Posted by timothy from the only-have-eyes-for-u dept.
twofishy writes "'To avoid the confusion caused by renumbering releases,' Oracle has announced that it is adopting a new numbering scheme for JDK 5.0, JDK 6 and JDK 7. 'The next Limited Update for JDK 7 will be numbered 7u40, and the next 3 CPUs after that will be numbered 7u45, 7u51, and 7u55." The vendor notes that a more elegant solution would require the changing of the version numbering scheme to accommodate different kinds of changes (for example by using 7u44-2 ). However this cannot be implemented outside of a major release, since doing so might break existing code that parses version strings (possibly including the Java auto-update system)" Here's Oracle's announcement.

      Because programs are used to decode/encode the name. It's the same problem with Y2K, user agent strings, and so on. When programs expect data in a certain format, such as two digits for years or a single number after a u in a version string, they don't react well when the format is changed. RTFA.

        They are using an incremental number on the RHS (right hand side) of the "u" seperator, and that number may represent either a critial patch update or it might be a new minor version. The problem arrises when they attempt to associate FUTURE releases with stuff in bugtrackers and their ilk. They could have more CPU releases than normal releases, making the CPU minor release number much higher than the planned normal release, causing a bunch of confusion.

      Because the old numbering system of incrementing by 1 was far too complicated. The new system is much easier to understand:

      * Limited Update releases will be numbered in multiples of 20.
        * We intend for Critical Patch Updates to continue to use odd numbers. The numbers will be calculated by adding multiples of five to the prior Limited Update and when needed adding one to keep the resulting number odd.
        * Updates containing Norton instead of McAfee will be prime numbers
        * If an update actually contains intentional regressions, it will end in a 9. We recommend you do not install these updates.
        * If the update number is a prime but also a member of the fibonacci sequence, it is considered a "surprise" update: It will be automatically installed, and will contain 1 or more undesirable features. It may also install the ask toolbar.

      Obviously this system is far superior.

      • The way developers have been doing it for decades, using the de facto standard of major.minor.build version numbers.

        IOW, JDK 5 uses 5.x.y numbers, JDK 6 uses 6.x.y numbers, JDK 7 uses 7.x.y numbers. X is incremented for feature releases and resets Y to 0. Y is incremented for security releases.

        Simple. Easily parseable. And it the ways things used to be done before the whole stupid "my number needs to be bigger than your number, logic be damned" movement started.

        • They pretty much do that, just with a useless prefix and an _ instead of . as the last delimiter.

          So instead of major.minor.build it is 1.major.minor_build, which means I could take your statement and easily alter it to read:

          JDK 5 uses 1.5.y_z numbers, JDK 6 uses 1.6.y_z numbers, JDK 7 uses 1.7.y_z numbers. Y is incremented for feature releases and resets Z to 0. Z is incremented for security releases.

    It was easier to change the version numbering scheme to break all the current malware rather than fix the myriad of holes in the code.

  • Why not just do a normal numbering scheme? If you dig into their packages, they sometimes claim stupidly to be version 1 of Java 7 update 17. WTF? Instead of that, how about Oracle just acts with some sanity and call it v. 7.17?

    If you need sub versions of 7.17, then call it 7.17.1 and 7.17.2. You know, a sane person might do.

    Or how about we all just drop Java since it's terrible and the cause of too many security problems?

    • You know, that does sound normal.
      But you're forgetting that Java 7 is actually Java 1.7, much like Java 6 was actually Java 1.6, and Java 5 was actually Java 1.5, etc.
      So there's that implicit "1." that you need to prefix to these version numbers.
      So that sentence in the summary should read more like:

      "The next Limited Update for JDK 1.7 will be numbered 1.7u40, and the next 3 CPUs after that will be numbered 1.7u45, 1.7u51, and 1.7u55."

      I can't wait to see what happens when they finally make it to Java 2.0... Will it be "Java 0"?

      • It doesn't really change the basic idea. In fact, I think it makes my point even stronger.

        If it's Java 1.7, why refer to a version as 7u40-3 version 1.0? Are you ever going to have a version of Java 1.7 that you're calling 7u40-3 version 2.0? That's insane.

        Just call it 1.7.40.3. Or really, make it simpler than that.

  • I would submit that this is somewhat sensible and that the switch from 1.5 to 5.0 back in the Sun days was far more confusing.

  • Or do we not have numbers that go that high?

  • Are their releases really called CPUs?
    If so, that is so amazingly stupid it appears actually designed to confuse.

  • Microsoft - One big version number. One little one. .Net Framework 2.0, 3.5, etc... easy to know where you are. Security patches don't alter the name unless they're a service pack. Then it would be .Net 3.5 sp 1 whatever. You at least know that as long as you have the update service running you are fully patched up and manually running it will make sure. 7u45 is freaking Chinese - it sounds like something that should be on the side of a submarine. Imagine trying to say one of these numbers on a phone to so

    • except the little problem of major component updates coming in v3.51 and the server OS being released with v3.5 on it,so many of your bleeding-edge programs wouldn't run.

      I think they fixed this by simply reducing the amount of development going into .NET, thereby reducing the frequency of .net releases.

      • Actually the .Net philosophy to me seems the polar opposite of Java. .Net releases seem further apart but seem to work better and have more integrated functionality. Personally... after using both for a long time C# + .net wins.... The portability comment isn't even an issue anymore really... Mono is working well in most cases (the gap is mostly in the latest incarnations of asp.net and MVC) and is fast enough to run games so it is fast enough for any business use at least in my mind. Personally, I dislike

        • True, .net is much better than Java, but I think much of that is down to the tooling - try writing C# code in notepad!

          They're both still pretty inefficient though, I've played a couple of games written in C#/XNA, they're ok, but there's a lot of grinding at startup and a lot of sluggishness after you've played for a while. Could be just general poor programming practice from games devs, but there's a fair amount of language "assistance" there.

  • From TFA:

    Is this the long-term solution?

    This solution is a compromise to create predictable release numbers for future Java releases, leave version numbers available for unplanned releases needed to address security alerts, and maintain backward compatibility with systems that expect the version number to have only a family number plus a single “update” number. It will be the new standard for the affected version.

    A more elegant solution requires changing the version format of the JDK to accommodate multiple types of releases. To avoid incompatibilities with existing code however, a change in the version string format needs to be implemented on a future major Java release and will have to be documented and communicated with adequate time to allow software developers to prepare for the change.
    Is this the long-term solution?

    This is a workaround. Oracle is being plain about this and at least making an effort not to break applications.
