In terms of major new whiz-bang features that you can show off to a corporate executive or a customer? You're right, not much new. But in terms of making the language suck less to use, Java 7's try-with-resources, Java 8 lambdas, and Java 8 default implementation of interface methods are all hugely helpful. And Java EE is now possible to use without XML hell, just a few annotations and you're all set. They can't change too much, if Java EE10 completely reinvents Java EE then companies completely lose the value of their previous investment in the technology. Likewise one business advantage of Java is that you can compile Java 1.1 code with the Java 8 compiler, so some of the coolest possible advances to the language would take that away.
But what I really want to see is the language as an open standard, so everyone can get the same benefits we see from the GCC vs LLVM competition. As long as Oracle thinks they can make money by avoiding that, it will never happen.
Well, I have two additional wishlists for Java 9 or 10: default language annotation @g @s and @gs on instance variables for auto-generating a public getter, public setter, or both at compile time without making me (my IDE) clutter up the source file by creating one for me and syntactic support for tuples. I think those two things would go a long way towards simplifying the language without hurting how readable code is.
