Are new systems being constructed in Java .. when starting on new projects Java was at one time (about 6-8 years ago) the leading alternative for Corporate IT (if they weren't a Microsoft shop). I doubt it very much.
Oracle is playing this not-so-good role, that Microsoft used to play, under Steve Ballmer, monopolistic, and evil.
I found Java hideous, the gratuitous OOP taken to extremes put me off. Spring came in, and you had class names that were a hundred characters long - your actual line of code was shorter than the class name. The problem with Java (and every programming language has its own achilles heel) - is everything has be class oriented - however much you try to bolt on, on top of that , to make it seem not so. . Java kills creativity, and expressiveness in software by its bloated syntax and OOP. We took up Java because at the time alternatives were few, but now its on its way being the new Cobol - this will sound ridiculous if you still are fully or partially, inside its bubble
I ran from our Java shop. My software architect mocked me "you'll be back in 6 months" - instead, he quit the Java shop and stuck his head outside of the Java bubble and realized there was life outside.
