- Change jvm version and sdk version in the parent pom.xml to GraalVM 22.1.0 and see test succeed at runtime. Behavior of reachibility handlers was changed to run concurrently by default as of GraalVM 22.2.
For some reason, the access.registerMethodOverrideReachabilityHandler() method gets invoked in GraalVM 22.1.0 but not in GraalVM 22.2.0.
Workaround: Disable concurrent reachability handler by providing the following option to the native-image builder:
-H:-RunReachabilityHandlersConcurrently
(1) Run export USE_NATIVE_IMAGE_JAVA_PLATFORM_MODULE_SYSTEM=true before mvn test -Pnative also results in same failure:

No, the error is reproducible with GraalVM 22.3.1 as well. We get the following error when -H:-RunReachabilityHandlersConcurrently is removed.
