如何为JPMS实现ModuleReader?

ModuleReference ref = new ModuleReference(moduleDescriptor, Paths.get(path).toUri()) {

@Override
public ModuleReader open() throws IOException {
    ModuleReader moduleReader = new ModuleReader() {
        @Override
        public Optional<URI> find(String name) throws IOException {
            //LINE X
            throw new UnsupportedOperationException("Not supported yet.");
        }

        @Override
        public Stream<String> list() throws IOException {
            throw new UnsupportedOperationException("Not supported yet.");
        }

        @Override
        public void close() throws IOException {
            throw new UnsupportedOperationException("Not supported yet.");
        }
    };
    return moduleReader;
}

};

LINE X /home/Sam/temp/foo-1.jar!META-INF/temp.txt 或者什么?
