Libraries, dynamic Java features, 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

- 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
