This was testing against a simple unpackaged class in my home directory. All the dependencies were javafx modular ones.
There was definitely no dependency on a /Pictures package where there would be any need to look any further on this path.
Is this scanning every directory off a class path one on the chance there might be a java class file that is a dependency?
