An application using JDK dynamic proxies throws runtime errors when running as a GraalVM native executable because proxy classes were not generated ahead of time. How are dynamic proxies configured for GraalVM Native Image?
| Checked | Without skill | With skill |
|---|---|---|
| The configuration specifies registering proxy interface lists in proxy-config.json or reachability-metadata.json. | Missed | Passed |

Expert skill for building high-performance native executables from Java applications using GraalVM Native Image, dramatically reducing startup time and memory consumption.
GraalVM Native Image compiles Java applications ahead-of-time (AOT) into standalone native executables. These executables start in milliseconds, require significantly less memory than JVM-based deployments, and are ideal for serverless functions, CLI tools, and microservices where fast startup and low resource usage are critical.
This skill provides a structured workflow to migrate JVM applications to native binaries, covering build tool configuration, framework-specific patterns, reflection metadata management, and an iterative approach to resolving native build failures.
Use this skill when:
ClassNotFoundException, NoSuchMethodException, or missing resource errors in native buildsreflect-config.json, resource-config.json, or other GraalVM metadata filesRuntimeHints for Spring Boot native supportBefore any configuration, analyze the project to determine the build tool, framework, and dependencies:
Detect the build tool:
# Check for Maven
if [ -f "pom.xml" ]; then
echo "Build tool: Maven"
# Check for Maven wrapper
[ -f "mvnw" ] && echo "Maven wrapper available"
fi
# Check for Gradle
