Micronaut
Micronaut is a JVM(Java, Groovy and Kotlin) framework similar to Spring Boot or Quarkus. Micronaut is modular and blazing fast. It has a minimal memory footprint and is a bit cleaner API compared with Spring Boot for instance. Micronaut does Reflection based IOC(with Cache). Micronaut also has GraalVM support. Micronaut is a non-blocking IO and has a Reactive API based on Netty and Rectivex projects. Today I made a quick video going trought the Micronaut API DEMO I made.
