GraalVM static initializer -- unsure if actually working?

I'm doing something very similar as to what is being done in this example project. However, it doesn't seem like my classes are being initialized correctly.

Simply, I'm just trying to collect a list of classes, based on some filtering, and build a map of those classes for use later.

Here's the code for com.mycompany.MyClass, that passes a unit test successfully without native compilation.

  public static Map<String, Class> = new HashMap<String, Class>();

  static {
      List<String> prefixes = Arrays.asList(...); // list of class prefixes

      List<ClassInfo> classInfos = new ArrayList<ClassInfo>();

      for (String prefix : prefixes) {
          try (ScanResult scanResult = new ClassGraph()
                  .disableModuleScanning() // added for GraalVM
                  .addClassLoader(ClassLoader.getSystemClassLoader())
                  .enableAnnotationInfo()
                  .enableMethodInfo()
                  .acceptPackages(prefix)
                  .initializeLoadedClasses()
                  .scan()) {
              ClassInfoList classInfoList = scanResult.getSubclasses(baseType);
              // snip some other filtering and restrictions that don't matter
              classInfos.addAll(classInfoList);

              for (ClassInfo classInfo : classInfos) {
                  Class<Message> clazz = (Class<Message>) classInfo.loadClass();
                  try {
                      nameClassMap.put(name, clazz);
                  } catch (InstantiationException e) {
                      throw new RuntimeException(e);
                  } catch (IllegalAccessException e) {
                      throw new RuntimeException(e);
                  }
              }
          }
      }
  }

When running the native test, I've done the following:

First, I've used the build options to ensure this static initializer is actually called:

  "-march=compatibility",  // we want native mode here, but active bug related to LZCNT prevents this.
  "--strict-image-heap",
  "-H:+UnlockExperimentalVMOptions",
  "-H:Log=registerResource:3",
  "-H:+BuildReport",
  "-H:+PrintClassInitialization",
  "--initialize-at-build-time=com.mycompany.MyClass,io.github.classgraph.,nonapi.io.github.classgraph.",
  "-H:ReflectionConfigurationFiles=${nativeImageDir.absolutePath}/reflect-config.json",
  "-H:ResourceConfigurationFiles=${nativeImageDir.absolutePath}/resource-config.json",

Then, using the PrintClassInitialization CSV result, I verified that the class is being included/initialized at build time:

com.mycompany.MyClass, BUILD_TIME, from command line with 'com.mycompany.MyClass'

However, when I run the native test, the static map that I am initializing is empty -- am I missing an obvious step?

Thank you for your help!
