- 16. Libraries, dynamic Javafeatures, and Native Image • Libraries might be Native-Image friendly out of the box • twitter.com/YunaMorgenstern/status/1729039787351536084 • Libraries might include config for Native Image: • github.com/h2database/h2database/blob/master/h2/src/main/META-INF/native-image/ • Libraries might contain config in the Reachability Metadata Repository • github.com/oracle/graalvm-reachability-metadata/tree/master/metadata/io.netty • You can use framework support to produce custom “hints” for Native Image runtimeHints.resources().registerPattern(“config/app.properties”); • You can use the Tracing Agent to produce the necessary config automatically • graalvm.org/latest/reference-manual/native-image/metadata/AutomaticMetadataCollection/ • You can provide/extend config for reflection, JNI, resources, serialization, and predefined classes manually in JSON: • graalvm.org/latest/reference-manual/native-image/metadata/#specifying-metadata-with-json Happy path; most of the cases Custom code/ libraries @alina_yurenko

AOT at thespeed of JIT 🚀 • Profile-guided optimizations Collect and use profiles to optimize for the specific runtime behaviour of your application • ML-enabled PGO Use a ML model to automatically predict the profile of the application • G1 GC Optimize GC for peak throughput and improved latency • `-march=native` Optimize for the specific hardware features of the machine you’ll be running on @alina_yurenko

- 24. Recommendations • Migrate 🚀 •Add Native Build Tools • Alternatively, use recent versions of frameworks • Evaluate libraries: graalvm.org/native-image/libraries-and-frameworks • Build and deploy 👷 • Build and test on GraalVM as the JVM, build with Native Image closer to the deployment • Quick build mode with `-Ob` • Use CI/CD systems (e.g. GitHub actions) for deployment and cross-platform builds • Monitor • jvmstat, JFR, JMX, Micrometer, cloud vendor solutions • Run faster 🚀 • PGO • ML-enabled PGO • G1 GC • `-march=native` @alina_yurenko

- 26. • Reduced attacksurface area due to dead code removal— unused classes, methods, and fields not included in executable Improved Security • Not vulnerable to JIT compiler attacks all code is AOT compiled • SBOM supporting industry standards Embedded in executables CycloneDX format • Not vulnerable to deserialization attacks via class loading—executable includes only required and specified classes Reduced Attack Surface 🛡 @alina_yurenko
