Call this unpopular opinion (probably gonna get downvoted anyway), but the amount Oracle gets paid because lazy-devs are well, too lazy to read which JVM arguments should they put to their deployment, requiring hand-holding by the Oracle-support team.
I understand in the olden times there were javax.* and JavaEE, but nowadays, especially in the newer JDKs, these are completely gone. Whoever maintains Java 1.6 in their core infrastructure already doomed, regardless of Oracle asking them $$$ or not.
edit: I know various Java-devs which are "runs on my machine" mindset. As a DevOps engineer, most of the production outages I took care of were avoidable by removing this mindset and actually testing the code in a sandbox environment...
I've had an ongoing debate with a guy who is supposedly senior java dev of 20+ years that doesn't understand the most basic aspects of concurrency, and codes "worked on my local" style and engages in obnoxious blame games with DevOps and infra teams about how his application works totally fine spinning up 10,000 threads on his 16 core macbook, but for "some reason" craps out in production running on a 1 vcpu allocated container. At least a year of back and forth on this and he doesn't understand why. Wish I was making it up.
