As a Java Dev of 15 years, through my own experience, almost all of these points I have discovered through hard fought bugs and trying to find a way to reduce the causes of them in the future. Final by default is the biggest, bc it removes some of the most basic concurrency errors implicitly. Awesome post. It also is pointing out things that in some other languages (e.g. Python) are implicitly impossible to achieve, and others which some new languages (e.g. Rust) have built in from the beginning, like never use null. Well done.
