What versions of software are you on?
In a recent thread on TSS, 2 posters (Andrew Lombardi and Augustienje Bloem) got into it a little bit about when things were released, and how long it should be before you think "okay, you're on something too old to really consider any more, update already." It was in context of JSF 2.0, where Mr. Bloem was saying that 2.0 came out in June 2009, people should stop blaming JSF for the problems of 1.0.
Mr. Lombardi had this point:
How many companies still use JDK 1.4?
His implication was "a bunch."
Mr. Bloem responded with:
It's another debate really, but the short answer: surprisingly few. It's a bit of an urban myth that the majority of big enterprises are still on 1.4, while in reality 1.4 has been EOL'ed a LONG time ago and big enterprises don't like running on EOL stuff.
Now, that's something else. Every time I find another person who says they're on 1.4, it's a surprise and I think "that's too many people on 1.4." But it happens - enough that I'm always a little surprised. I don't think there's any reason anyone should ever even be on 1.5 any more, but they are, and for reasons I can't really say are wrong (usually, updates are scary, which for a big company is probably true.)
As for me, I'm on Java 1.6.0_23 (upgraded as soon as it came out, to try to see if Yakov Fain's problem was real or not, and it wasn't, he's an idiot sorry) ; I use Glassfish 3.0.1 as my Java EE container even though I usually just stick to the basic servlet API, I use Maven 3.0 (haven't seen a reason to upgrade to 3.0.1), IDEA X and Eclipse Helios, Hibernate 3.6, and Spring MVC 3.0.4. And a host of other things like it.
The versinos of most of the software isn't important, but the JVM and the Java EE versions are. So I created a survey to try to figure out which versions people use. It's just for information's sake, I'm not selling anything; I'll post the results here on TSS when I get to an interesting threshold, as long as people are interested.
