Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Java 21: The Nice, the Meh, and the Momentous
It is not. Blocking IO (with some exceptions mentioned in the JEP) will automatically be translated by the runtime into non-blocking IO when it occurs on virtual threads, and no OS threads will be blocked. You can have a million threads blocking on a million sockets (obviously without creating a million OS threads): https://github.com/ebarlas/project-loom-c5m
You can't do that with thread pools. You could achieve that scalability with async code, but then observability tools will not be able to track the IO operations and who initiated them, but with virtual threads you'll see exactly what business operation is doing what IO and why.

Don’t call it a comeback: Why Java is still champ
That might change in JDK 21 (with virtual threads). See this https://github.com/ebarlas/project-loom-c5m . It achieve 5 million persistent connections (again depends on the server capacity and kernal tuning) using normal simple blocking code (https://github.com/ebarlas/project-loom-c5m/blob/main/src/main/java/loomtest/EchoServer.java) . It's a far better better programming model compared to JS async/await.

Javalin – a simple web framework for Java and Kotlin
One of the good things about it is that using asynchrony is optional. If you don't have to call out anywhere to build the response, processing can all stay in the handler's calling thread. If you do, you can return a future and have the library handle the async for you.
One downside is that it is based on Jetty which isn't considered the most performant backend. A lib with a similar API but based on Netty is Jooby [1] which scores well in the Techempower benchmarks.

Is the Spring framework too heavy and over-designed?
Jooby and Helidon SE are among the best.

RIFE2 web framework under development
The code snippet gave me a vibe like it was jooby Looks cool, I suggest maybe start incorporating Project Loom virtual threads in the future.
- Java modern frameworks choice
- Latest version of Microhttp, an event-driven, zero-dependency, pure-Java web server with 500 LOC, capable of 1,000,000+ requests per second on commodity EC2 hardware.

The Flask Mega-Tutorial
Speaking of backend development, recently I gave Jooby[1] a try after discovering it was one of the world's top performer in Tech Empower's web framework benchmark[2].
Surprisingly enough, it's terribly easy to put together a REST API with Jooby. I wonder why it's adoption rate is so low.

What is the current state of the art for efficiently handling blocking requests in Java/Spring?
Do you need to use Spring btw? If you want to broaden the tool selection I've had great success with i.e Jooby (https://jooby.io/) together with Kotlin coroutines. Another alternative is the KTOR framework.

Java Equivalent of Express.js for REST
Jooby I think is the best bet. https://jooby.io/ watch out for jooby dot org I think someone sniped the domain.

Fully Static Java Webserver - Is this a bad idea?
Spring Boot or JAXRS. I personally use Jooby a lot which is similar in style to spark but has annotation support and isn't a singleton.
What are some alternatives?
