Summary
-------
The GraalVM native image (./gradlew nativeCompile) builds successfully, but the
resulting `codeanalyzer` native binary cannot analyze any project. Every run that
performs source analysis fails at startup with a JavaParser reflection error.
Environment
-----------
- GraalVM CE 21.0.2 (native-image 21.0.2)
- graalvmNative gradle plugin 0.10.4, built with --no-fallback
- Binary: build/native/nativeCompile/codeanalyzer (approx 63 MB)
Steps to reproduce
------------------
1. Install a GraalVM with native-image (e.g. sdk install java 21.0.2-graalce).
2. ./gradlew nativeCompile
3. ./build/native/nativeCompile/codeanalyzer -i <any-java-project> --emit json -a 1
Expected
--------
analysis.json is produced, same as `java -jar codeanalyzer.jar -i <proj> --emit json -a 1`.
Actual
------
Exception in thread "main" java.lang.NoSuchFieldError: variables

Root cause
----------
JavaParser drives its AST validators through a reflective metamodel:
PropertyMetaModel.getValue uses reflective Field access on AST node fields such as
`variables`. Under the native-image model these classes and fields
must be registered for reflection at build time. The project reflection config
(src/main/resources/META-INF/native-image-config/reflect-config.json) does not
cover the JavaParser AST node classes and their declared fields, so the lookup of
the `variables` field throws NoSuchFieldError at runtime.
Suggested fix
-------------
Regenerate / extend the native reflection metadata for JavaParser:
1. Run the GraalVM tracing agent against a representative analysis run and merge
the captured config:
java -agentlib:native-image-agent=config-merge-dir=src/main/resources/META-INF/native-image-config \
-jar build/libs/codeanalyzer.jar -i <sample-project> --emit json -a 2
This captures the reflection/resource/proxy/JNI entries the parser needs.
2. And/or hand-add the JavaParser AST classes (com.github.javaparser.ast.**) with
allDeclaredFields to reflect-config.json.
3. Add a native smoke test in CI that runs the native binary with --emit json on a
tiny fixture, so this regression is caught going forward.
Impact
------
- The native build itself succeeds; this is purely a runtime reflection gap.
- Blocks all native-image analysis, including --emit json and --emit neo4j end to
end. The fat jar (java -jar) is unaffected.
