In general it's interesting times for Java. With all of language improvements from Kotlin/Scala, and upcoming Go-like concurrency it really feels like a renaissance for the language.
Project Loom’s virtual threads (without dedicated OS threads and stacks), which will hopefully relieve devs from manually doing a CPS transform of procedural code into chains of futures for thread pool workers to complete.
I'd say that first Java renaissance is Java 5 with generics. Second Java renaissance is Java 8 with lambdas. IMO third Java renaissance will be with re-introduction of green threads.
