I’m not sure that decreasing demand in Java is what led to a Jetbrains Java IDE overtaking Eclipse. The total pie may be smaller, which in itself is probably debatable and I’m not going to bother researching, but I believe the takeover has more to do with an active android programming ecosystem than any of the other factors mentioned in the article. It would be interesting to see a breakdown between IntelliJ editions with Android Studio broken into its own product line.
