Using the Module as the caller granularity is reasonable here to find the resource bundle.

DefaultLoggerFinder.java
 135         static boolean isSystem(Module m) {
 136             ClassLoader cl = AccessController.doPrivileged(new PrivilegedAction<ClassLoader>() {

This isSystem method should check if the class loader is platform class loader (ClassLoader::getPlatformClassLoader) or its ancestor. There are several copies of this method. Better to have one single copy of this method shared for other classes to use?

Nit: you can use the diamond operation PrivilegedAction<>.

LazyLoggers.java.
line 294                 return new LazyLoggerAccessor(name, factories, module);

I spot several long lines in LogManager.java, Logger.java, System.java and tests, maybe other files.  It’d be good if you can wrap the lines to help side-by-side review.

Other that that, looks good.
