Java consistently introduces lots of exciting functionality into the language. That's a big part of my dislike and active avoidance of it.
Let me be clear: Do I think it is possible to write good, clear, performant code in Java? Of course - Java can be used to write great software. The problem is that in Java there exist an extraordinary set of variations of a sufficient implementation, many of which are package protected abstract static horrors shows. And that will manifest over time if you add different individual developers. Else the project must engage in bureaucracy and control, where you have meetings over style conventions or hardline architects who come to constrain the joy of programming in the devs.
Its much better when the language itself constrains you, then everyone can just move on. I feel Go, though certainly not perfect, meets this niche.
In the specific case of java however I don't think this applies much; the vast majority of improvements are aimed at under the hood optimisations rather than syntax. And I feel that any changes in syntax have been quite incremental, intuitive, and reasonable.
AND they stay around as preview features forever, so this may inflate the perception of features entering the language, when in fact it's the same one feature being mildly iterated on.
E.g. the main syntactical change in this version seems to be the use of primitives in switch statements, which was already discussed for a while, and is itself a meaningful change brought about by the introduction of switch expressions.
