Here are the latest results from the DrJava Survey. Since the last time I looked at the survey, developer builds were not relevant, I did not distinguish between developer builds and official releases this time, or look at the different DrJava versions that were used.
An analysis of the data is below, but here are my conclusions:
- We need to test on Windows Vista. One third of our users now have Vista.
- We need to test on MacOS Leopard. There are four times as many users with 10.5 than with 10.4.
- Only 205 users ran Java 1.4 — about one percent. Abandoning Java 1.4 should not cause any problems.
- Most users (85%) are now working with JDK6.
- 66 users ran Java 1.7, so we should keep an eye on that.
