Overview

When a hint such as graphql/*.* is registered for resources that are looked up via classpath scanning using a pattern such as classpath*:graphql/**/*.graphqls, an appropriate pattern is in fact registered in the generated resource-config.json file for GraalVM native images; however, classpath scanning fails since GraalVM currently does not make the graphql directory automatically available as a classpath resource.

This can be very confusing and cumbersome for users since a file such as graphql/schema.graphqls will not be discovered via classpath scanning even though the file is present in the native image filesystem.

To address this, we should automatically register resource hints for enclosing directories for a registered pattern.

If the GraalVM team later decides to perform automatic directory registration, we can then remove the code introduced in conjunction with this issue.
