    Indeed. So the story is, he wrote some code, and had an unexpected problem. And lots of Java code.

    Wow, I can feel the rush.

  • Stark_ (unregistered) in reply to OMG

    But what about a Cache that causes an OOM rather than uncache data?

  • Qwerky (unregistered)

    There are several WTF more noteworthy than having your result implement Serializable.

    1. Writing your own cacheing mechanism when there are some great caching tools that just work out of the box like ehcache.

    2. Passing the cache to another machine? Isn't that why you have a cache in the first place, to avoid having to do this?

    3. System.exit(1) in the exception catch block.

  • Matteo (unregistered)

    Solution to this: use Java's RMI instead of simple Serialization?

    Of course, you would have to refactor the code to avoid a lot of message-passing, and that would change the design of the system, but it should avoid this problem.

  • Zog (unregistered)

    That's not real Java....where's the multiple, nested AbstractFactoryPatternGenerator classes then??!?!!

    On the other hand, that probably saved gigabytes of source code let alone run-time....

  • TBD (unregistered)

    Well, the real and oly wtf in this meh wtf is that we still do not know what happened to Aargle ...

  • WL (unregistered)

    And that's why you always perform an extended load-test on a setup as will be deployed, not just on a single machine.

  • Java Expert (unregistered)
    • private Map<Long,NewReferenceData> localRefDataCacheHandle;
    • private transient Map<Long,NewReferenceData> localRefDataCacheHandle;

    Bug fixed. Maybe later a sensible design can be sought to avoid this entirely.

    Don T. Aargle was having a bad day working for the president's daughter Tye. He had to implement a cache solution in Java rather than his native language PHP.

    So it's passing 100mb of data back and forth for every transaction, and nobody noticed it was a little sluggish?

    WTF!

  • cybaz7 (unregistered)

    Yo Dawg, I heard you like caches so I created a reference cache for the sub-cache of the master cache

    If you can even call this a cache. Normally a cache has some kind of size limit and replacement strategy.

    Matteo:

    RMI's IPC is based on serialization.

    I had to untangle a similar mess once that was used RMI. Because RMI calls look like ordinary Java calls, a sub-par programmer didn't see the data duplication caused by passing around huge Maps.

    I expect that by day's end, we'll see about 100 people chime in that they've seen this problem in some RPC-based project or another.

    I think every time you see something described as "transparent," you should imagine a plate-glass window. Then imagine what happens to an idiot who tries to walk through it. Best case: a bruise or two. Worst case: glass and blood everywhere.

    There's nothing in the definition of a cache that mandates any kind of limitation strategy. That's just common sense. If common sense were common, this site would not exist.

    What kind of cache is copied to another system and put in a cache there? Just send the data required for the remote call...

    Aargle re-wrote the code, it performed 1ms slower than the original code so he got sacked.

  • Ben Jammin (unregistered)

    Apparently some people didn't follow the link hidden way down in the depths of the page source (and comments.)

    Well, spoiler alert: Those headaches Aargle was getting are actually a genetic abnormality that heighten his senses and increase his heart rate to over 400x the normal rate, so he joins a group of assassins led by Morgan Freeman (mainly because who wouldn't let Angelina Jolie kidnap them in a Dodge Viper.)

    Tye, however, is targeted by some assassins (different group) who have taken her code and used it for nefarious purposes. Thank goodness Bruce Willis, a local detective with a stunning career of saving the nation from terrorists multiple time, was just about to arrest her, because together they stop this other group of assassins (Bruce by running a car into a helicopter, and Tye by slowing them down with her expensive, sluggish code.)

    Not really, you just quoted different parts of it. Here's the full story:

    Those headaches Aargle was getting are actually a genetic abnormality that heighten his senses and increase his heart rate to over 400x the normal rate, so he joins a group of assassins led by Morgan Freeman (mainly because who wouldn't let Angelina Jolie kidnap them in a Dodge Viper) while he re-wrote the code.

    Tye, however, is targeted by some assassins (different group) who have taken her code and used it for nefarious purposes, finding out that it performed 1ms slower than the original code. Thank goodness Bruce Willis, a local detective with a stunning career of saving the nation from terrorists multiple time, was just about to arrest her, because together they stop this other group of assassins (Bruce by running a car into a helicopter, and Tye by slowing them down with her expensive, sluggish code.)

    Incidentally - I'm pretty sure most of the people who are complaining (myself included) did already read the pre-published second part, but we're not going to let that stop us whinging about it; where would be the fun in that?

Aargle got sacked.

    Wait, the other assassin group weren't assassins at all. They were a couple of wannabe masked heroes posing as villains. One had a bunch of money and the other one could actually fight. Turns out, they can increase their heart rate too. Unfortunately for Angelina Jolie, poor scriptwriting would lead to their doom, because only an oriental can truly raise their heart-beat without misinterpreting binary patterns in a cloth because the loom is effed up and the contractor tried to fix it with PHP.

    Realizing the error of their ways, Angelina Jolie commits a multi-homicide-suicide and end their group, right as the rich loser from the other group learns that he too can raise his heart rate.

    Then the oriental kid from the 2nd group hits a switch on the car he made and it transforms revealing it's actually Stealth Jazz (a repaint of Jazz from the first movie for $14.99).
