Spring 6.1 now compatible with virtual threads and JDK 21

So far the responses have been lukewarm to negative. I'm all for a framework as big as Spring, blazing the trail to use Virtual Threads! I haven't used Spring Boot in a few years, and Webflux was a paradigm shift that didn't interest me. It'd be nice to see what this does for the framework.

I just wish there was an admin generator like django's

I keep reading negativity about spring. I got curious, am building the backend for a new startup with spring boot 3. It’s been a breeze. Everything works, great tooling, very mature software. Am I missing something? Will I regret this in six months?

I wonder if there will be any tools to detect pinning or synchronized use to help with the virtual threads transition.<p>Blockhound I have gound useful for detecting blocking in non blocking areas.

Moving the needle. But still as bloated as it can get.<p>Never was invested in anything beyond Java SE, now I&#x27;m never going to invest in Java SE again.

Somewhat off-topic, somewhat related:<p>Is Hibernate moving towards Java generics, about 2 decades after the fact?<p>Spring seems much bigger and seems to moving much more quickly, but it&#x27;s weird that Hibernate seems to still be stuck somewhere around Java-in-the-00s.

How’s performance? Is it better? Any benchmarks?

Spring has gotten so bloated. It seems like there&#x27;s no feature request they can say &quot;no&quot; to. Plus there&#x27;s multiple ways of doing the same thing. e.g. JPA, spring-data.<p>their call stacks between injected components are sometimes a couple dozen layers deep and it makes no sense.<p>they don&#x27;t provide easy upgrade paths between majors versions and they stop updating vulnerabilities on older major versions. I inherited some code that was using version x but had to be upgraded due to critical vulnerabilities. The vulns weren&#x27;t fixed in x or y but only z. I tried moving over and their cryptic unit test fixtures stopped working. No docs on migration. Spring is sort of like cancer.

All of these nice features of the JDK yet most Fortune 500 companies probably still using JDK8 or 9.
