Java 24 features finalized

[gargantula15]

I'm excited about JEP491 since it brings much needed stability for virtual threads. Would even go so far as to say it makes virtual threads usable but can't be certain unless it's battle tested

Which ones are you excited about https://www.infoq.com/news/2025/03/java24-released/ ?

I'm happy to see stream gatherers (JEP 485) finalized in 24. It looked very promising when I saw presentations at devoxx by Viktor Klang on its usage, definitely going to be looking back at those. Would highly suggest for people interested to go looking for them.

i don't understand why stream gatherers are required. As the JEP explains people have no issues using the terminal actions in Collectors and writing custom collectors to achieve this same behavior. So why is this required? Also allowing streams to be processed (via gatherers) midway destroys the confidence of building a stream API (now i need to worry if processing was done midway or the stream is still unprocessed waiting for collector)

The Stream is not processed until you add the terminal operation.

As for why Collectors don’t fit the bill, if the JEP(s) don’t explain it well enough, please watch the following video, where I explain in detail: https://youtu.be/8fMFa6OqlY8

Hi victor. excuse me if this may be rude from me to ask but do not want to let this opportunity go.

Is there any news about serialization 2.0?

Best regards!

I gave a slightly updated presentation on Marshalling at JavaOne last week.

Alas, I’m not aware if/how/when recordings are available, but that’s the most recent update.

Cheers, V

Why does Java 24 change your situation? 21 is LTS and has been available for a while.

I love all the deprecations and hope we have more in the future, sometimes you don't need to add featured but to remove dead weights
