One of my clients handles 90% of all the pbm routing in the US, which is millions of transactions per second. They started to completely modernize the application on java... primarily Spring Boot and Apache Geode. After some optimizations they are very happy with the performance and expressiveness of modern java.
Exactly right. Java has lots to improve on but there seems to be unsubstantiated hate towards Java on HN which I find contrary to what happens in the real world. In the real world companies find hiring Java programmers relatively easy (maybe not the best and brightest) who can get a project off the ground easily
