Graalvm

This one's built for Java developers shipping native binaries with GraalVM, covering Quarkus, Micronaut, and Spring Native. It walks you through the reflection config hell, resource registration, and build-time initialization that makes or breaks native compilation. The guidance spans testing in both JVM and native modes, Docker multi-stage builds, and debugging with the tracing agent when things go sideways. If you're chasing sub-second startup times and minimal memory footprints for microservices or serverless, this gives you the framework-specific patterns and GraalVM quirks you need. Honest take: native image builds are still finicky, but this at least organizes the gotchas in one place.
