maven-bundle-plugin doesn't handle multi-release jars

while setting up JPMS for opencsv in a multi-release jar I found that the latest maven-bundle-plugin incorrectly warns about sources in the wrong directory.

I'm correctly using the latest maven-compiler-plugin and maven-jar-plugin with a module-info.java in ${project.basedir}/src/main/java9 which allows having the main source be compiled with Java 8 while also including a module-info.java that gets compiled targeting Java 9:

However the bundle plugin doesn't recognise this as being a valid setup:

[INFO] --- maven-bundle-plugin:5.1.9:manifest (bundle-manifest) @ opencsv ---
[INFO] No MANIFEST.MF file found, generating manifest.
[WARNING] Manifest com.opencsv:opencsv:jar:5.7.2-SNAPSHOT : Classes found in the wrong directory: {META-INF/versions/9/module-info.class=module-info}
