Java 7.0 for personal projects and experimentation because I can and I love using the latest and greatest. I used Java 6.0 since around build 40 and was very happy with its stability even then.
Java 6.0 for new open source stuff I write at least until 7.0 is released and available for a bit of time.
Java 1.4 for work, because that's what we have to use. I hope we've moved on to 5.0 by end of next year but I'm guessing it's not going to happen by then. |
