I'm working for a european org that is close to government and has been granted immortality by law, so market forces only apply in a very dampened capacity. They pay a premium for Commercial Java to be able to ask for certain features or support. ...Oracle always declines them with a variety of excuses, so there's no upside. Their older developers say they use features specific to the Oracle version, but I've never seen that, it works fine with OpenJDK, Jetbrain's, Amazon's or Microsoft's JDK
