• It looks like the Opengauss JDBC Driver is looking for javac under the GraalVM Native Image, which is a bit strange.

Wait for me to raise a separate PR to introduce the SCM proposal on GraalVM CE For JDK22.

• SCM helped find the critical classes.

org.graalvm.nativeimage.MissingReflectionRegistrationError: The program tried to reflectively access class

   org.codehaus.janino.CompilerFactory

 without it being registered for runtime reflection. Add org.codehaus.janino.CompilerFactory to the reflection metadata to solve this problem. See https://www.graalvm.org/latest/reference-manual/native-image/metadata/#reflection for help.

• For getDeclaredClasses(), there is no documentation referring to it, but it is indeed documented in the source code, see https://github.com/oracle/graal/blob/vm-24.0.2/docs/reference-manual/native-image/assets/reflect-config-schema-v1.0.0.json#L96 .

org.graalvm.nativeimage.MissingReflectionRegistrationError: The program tried to reflectively access

   org.apache.calcite.rel.metadata.BuiltInMetadata.getDeclaredClasses()

 without it being registered for runtime reflection. Add org.apache.calcite.rel.metadata.BuiltInMetadata.getDeclaredClasses() to the reflection metadata to solve this problem. See https://www.graalvm.org/latest/reference-manual/native-image/metadata/#reflection for help.

• Although the following GRM has been defined,

{
  "condition":{"typeReachable":"org.apache.calcite.rel.metadata.BuiltInMetadata"},
  "name":"org.apache.calcite.rel.metadata.janino.GeneratedMetadata_CollationHandler"
}

• The generated classes are still not found under nativeTest. We may need to wait for shardingsphere to switch to graalvm ce for jdk23. In jdk23, GRM was revolutionized again.
