There Are Many of Us Spring Boot, and We Only Get Stronger
summary
Deep dive into AOT (ahead-of-time) compilation for Spring Boot: why teams use AOT to get faster startup, predictable and instant peak performance, and where it may not help. Uses the Excelsior JET AOT-focused JVM to show concretely how Spring’s dynamic features (custom class loaders, reflection, runtime bytecode generation/loading) can be made to work together with AOT-generated native machine code.
