The biggest problem with Java these days is java developers are not really good at all. I would say n the last 10 years 99 percent of "Java" devs cant competently read a stack trace.

Im not sure why anyone would improve this language when the developers are so frankly pathetic. Let them use 1.8. The ecosystem has improved. Devs have gotten worse.

Java has become a land of opportunists just trying to pass of their non-Java maybe non-programmer skills

Really curious what makes you say this. Do you see the same thing in other languages? I've worked with many great Java devs over the years and think I'm halfway decent myself after working with it for 16+ years. Are there some bad ones in between? Sure, but that's true of any language (especially javascript).
