Steps to reproduce

Hello,
Trying to copy a file from a GCP bucket to my application, I noticed that using the method Path#copy(Path, Path, CopyOption...) is throwing an exception with java 21, although it was working well with java 17.
Here is an example of code :

    public static void main(String[] args) {
        try {
            Path bucketSource = Paths.get(new URI("gs://my-bucket/file.txt"));

            //copy with FileOutputStream
            Files.copy(bucketSource, new FileOutputStream("./target/fos.txt"));
            System.out.println("copy with FileOutputStream : ok");

            //copy with Path
            Files.copy(bucketSource, Paths.get("./target/path.txt"));
            System.out.println("copy with Path : ok");

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

Execution with java 17 :

copy with FileOutputStream : ok
copy with Path : ok

Process finished with exit code 0

Execution with java 21 :

copy with FileOutputStream : ok
