Cannot configure reflection for graalvm with java when method has primitive types

[davireis]

Expected Behavior

As seen in https://guides.micronaut.io/latest/micronaut-graalvm-reflection-gradle-java.html, one can configure graalvm reflection through a reflect-config.json file or with a java file. The latter has the small advantage of giving some IDE help on typing the classes. Other than that, I would expect the two formats below to be strictly equivalent:

The json:

[
    {
        "name": "org.flywaydb.database.postgresql.PostgreSQLConfigurationExtension",
        "methods": [
            {
                "name": "setTransactionalLock",
                "parameterTypes": [
                    "boolean"
                ]
            }
        ]
    }
]

The java:

import io.micronaut.core.annotation.ReflectionConfig;
import org.flywaydb.database.postgresql.PostgreSQLConfigurationExtension;

@ReflectionConfig(
        type = PostgreSQLConfigurationExtension.class,
        methods = {
                @ReflectionConfig.ReflectiveMethodConfig(name = "setTransactionalLock", parameterTypes = { boolean.class })
        }
)

Actual Behaviour

For methods that take no parameters or that take a class as a parameter, the two forms are strictly equivalent, and my binary runs just fine. However, for a method that takes a boolean as a parameter, it seems the reflection is not registered with Graalvm when using a Java-based configuration, and I receive the error below. When using a JSON config, everything works just fine.

 [main] io.micronaut.runtime.Micronaut -  Error starting Micronaut server: Bean definition [javax.sql.DataSource] could not be loaded: The program tried to reflectively invoke method public void org.flywaydb.database.postgresql.PostgreSQLConfigurationExtension.setTransactionalLock(boolean) without it being registered for runtime reflection. Add public void org.flywaydb.database.postgresql.PostgreSQLConfigurationExtension.setTransactionalLock(boolean) to the reflection metadata to solve this problem. See https://www.graalvm.org/latest/reference-manual/native-image/metadata/#reflection for help.

Steps To Reproduce

1. In a micronaut project that uses reflection on initialization:
2. ./gradlew --no-configuration-cache nativeRun
