summary
Helidon 4 targets Java 21 virtual threads and replaces SE’s reactive core with a new greenfield Nema web server built for blocking/imperative code; benchmarks report Nema matches Netty’s raw requests/sec and pipelining “skyrockets” throughput, while MP running on Nema shows nearly 2x and up to 4x gains for HTTP/2+TLS in the presenter’s tests. The release adds Halidon Inject — compile-time, reflection-free injection with config-driven service instances and generated Java sources — plus a class-model generator for annotation-processor-driven code generation.
