Still on Java 8 at work :-/
For those who have upgraded, I assume Jigsaw is the main concern?

#142Looks like no type aliases still? Does anyone know if type aliases are anywhere on the road map for Java? Is there some philosophical objection to them?
Considering how heavily they have borrowed from Scala lately, I would have expected them to pick this up. I found them quite useful in Scala (and in Golang as well).

#143As a student most of the way through a Java course, I'm wondering what Java is still used for. Java applets are dead, Android is moving on to Kotlin (apparently Google got in legal trouble with Oracle even though Java is "open source?"), and I can't think of any desktop applications that use Java anymore.

Zero-GC Java looks lot of like Ancient C++ and in that case Modern C++ is far better because of RAII.
Most of perf profilers are horrible in HFT scene. You need to measure from processor level with Intel VTune.

Other languages have started to eat into Java's market share, but coincidentally a lot of them run on the same host VM as Java. For instance, Kotlin, Scala and Clojure are more and more frequently seen in backend, web and mobile development.
These languages are definitely much more "portable" depending on what your definition of portability is; the JRE runs on A LOT of systems and abstracts much of the underlying system away for you, meaning that IME you have to write a lot less platform-specific code if you're targeting e.g. Windows, macOS and Linux.
As for your edit, the licensing is a bit complex for Java but TL;DR if you install OpenJDK releases you do not need to worry yourself about licensing.

#145Java 16 for what? Does anybody really use > 8 in production?
Who still uses Java 8 in production? That is a serious risk. I thought everyone moved to 11 already. I use Java 15 in production in 3 projects.
Tons of folks in financial IT are on 8 - it is pretty stable and very common target for most of the libraries being used.

Basically there's six month feature releases but every five or six releases there's going to be an LTS release. Most companies use the LTS releases. Next big LTS release is later this year.
If you mention LTS you have to mention also vendor that provides it. Without it the only LTS is current java version: 16 right now and 17 in 6 months.
Huh? There's like several LTS vendors: Oracle, Amazon, and Azul to name a few.

A lot of Universities teaches Ancient C++ and developers start to hate it. The rant of Linus also caused huge disaster newcomers coming into C++ and that shifted people into Rust.

LTS stands for long term support. Nobody provides that for java 16

I have worked with Java EE (Enterprise Edition) for a few years. Java in the backend is probably the most common one when doing enterprise software.
Lets define it differently: Everything what is not an SAP System and is backend and is not Cobolt, is Java at least for automotive and banking. Automotive -> managing cars, service contracts, financing offers, accessories and for banking -> money management, insurance, contract management etc. You go to a shop and you wanna finance something? Might be a Java backend or Cobolt :D)
Spring/Spring Boot as a Framework got a lot of traction because Java specification process was just way slower and more boilerplate
And yes Oracle got fed up of doing Java for free for too long and if you wanna use an older version of java and still need patches, you will need to pay.
Luckily there is were java actually shows it strength which i have not seen in other languages: You define a specification, you get a reference implementation from someone and then everyone around it starts to build on those specifications.
This allows for different jpa (database access with java) implementations, different application server etc. It also allows for different companies to do their own JVM implementation/maintenance track/version.
From an ecosystem pserpective, the JVM itself (without java) also did a great job and shows how versatile it is. Close to what .net is doing but in a more free version. And you could throw .net/c# into the same similiar category as Java. Language feels similiar and if you are a MS company, you just use C# perhaps. But switching between c# and java is much easier than to other languages.
From all languages i know and worked with, i do like JVM based languages the most. golang is interesting but nothing i would wanna use for a big code base at all. C/C++ i would use if i need to because of tooling features, how you write it and how hard it is to write it good;
Java is fast, java has great tools for a long long time: Great Debugging features, great memory and performance analysis and tools, lots and lots of frameworks and architecture catalog.
PHP is written and used in business context like java but without the benefits of running on the JVM. I don't recommend it. Its not bad, its less boiler plate but its just not a nice well defined well designed language. Most shocking to me was the performance optimizations which were done a few years ago which shows how little interest in that language exists that you can just optimize it that much. What facebook did with PHP was just shitty and weird.
