Keynote: The Java Renaissance
summary
Claims that Java sheds its “slow, memory‑hungry” reputation with concrete tooling: build‑time optimization via Quarkus and Micronaut, GraalVM native images, and OpenJDK distributions from Adoptium. Measured results cited: Quarkus dev mode ~150–450 ms restarts and instant continuous testing (~372 ms), GraalVM native: 24 ms cold boot and ~22 MB RSS (40 MB binary), and OpenJDK Quarkus ~73 MB vs traditional stacks 136+ MB and multi‑second boots. Reproducible demos show 60–400 ms first responses for native and 0.5–2 s for JVM builds.
