RepositoryConfigurationExtensionSupport too strict in Spring Boot 4.0

[SledgeHammer01]

I'm working on a Spring Boot Starter for Hibernate Reactive. All works fine.

With Spring Boot 4.0 M1 (worked fine in Spring Boot 3.5.x), a client application no longer works because of this check in RepositoryConfigurationExtensionSupport.java:

	protected boolean useRepositoryConfiguration(RepositoryMetadata metadata) {

		if (metadata.isReactiveRepository()) {
			throw new InvalidDataAccessApiUsageException(
					String.format("Reactive Repositories are not supported by %s; Offending repository is %s", getModuleName(),
							metadata.getRepositoryInterface().getName()));
		}

		return true;
	}

The application includes spring-boot-starter-webflux, the starter does include:

    <dependency>
      <groupId>org.springframework.data</groupId>
      <artifactId>spring-data-jdbc</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.data</groupId>
      <artifactId>spring-data-jpa</artifactId>
    </dependency>

But Spring Data Jpa is required because that is where Specification lives for example.

YES, I am overriding protected boolean useRepositoryConfiguration(RepositoryMetadata metadata) in my custom config extension, however, JpaRepositoryConfigExtension ALSO gets run and that's the one throwing the exception.

Since JpaRepositoryConfigExtension lives in spring-data-jpa, there doesn't seem to be any way to prevent that from running.
