So does this fix the crashing issue with macOS Sonoma 14.4? https://arstechnica.com/gadgets/2024/03/usb-hubs-printers-ja...

I doubt Oracle would fix it, as this is definitely a kernel bug that breaks userspace. It is part of the POSIX spec what the JVM relies on, and MacOS is supposedly POSIX-compliant. So it should be Apple that fixed their bug.

Maybe my favorite feature in this release: https://openjdk.org/jeps/463 Finally solves the inscrutable Hello World program! Yes, it's just ergonomics for early beginners. But could be the difference in whether or not someone new to programming sticks with Java or not.

That sounds a lot like Top-level Statements in the .Net world. Personally I don’t use that feature because I’m old and get confused if things are magic but can certainly see the benefit for the newer devs.

My first Java programming course went over in detail about that piece of code and in a couple of hours taught me a lot of important Java concepts right away. Consider me not enthused about it.

Java continues to evolve to a bad Groovy.

Yeah, no doubt inspired by the .NET feature. I use it all the time for throwaway console apps.

It's kind of startling to see how many places still use Java 8, estimated at ~1/3 of projects according to a survey i just googled. And something like half that still use java 11.

Groovy itself is a bad Groovy.

Good that they got rid of the class/public static void/string[] Args boilerplate, but if they just went one step forward and declared implicit main function as top-level scope of a file, we could've got to a Python level of tersity. Just imagine!

    System.out.println("Hello world!");

Earlier quoted context omitted.

They will eventually bring value types to Java with Project Valhalla.

I wonder how long it will take. We’ve been waiting for ten years already.

Looks like we may see a first preview in Java 23, i.e. already this year.

It isn't a "Sexy" PL change, but a full foreign function interface will be a huge change. In my experience, relying on the old java JNI based libraries seems to be one of the biggest things that break in upgrades. So I am hoping this will reduce the maintenance burden of Java.

Boring changes like these are what keeps Java interesting.

New and shiny syntax sugar becomes stale real quick.
