The following demonstrates the issue with Zip FS and using URIs


Path zip1Path = Files.createTempFile("zip1", ".zip");
try {
    Files.delete(zip1Path);
    try (FileSystem zip1 = FileSystems.newFileSystem(zip1Path, Map.of("create", true))) {
        Path zip2Path = zip1.getPath("zip2.zip");
        try (FileSystem zip2 = FileSystems.newFileSystem(zip2Path, Map.of("create", true))) {
            Path nestedFilePath = zip2.getPath("test.txt");
            Path newPath = Path.of(nestedFilePath.toUri());
            assert nestedFilePath.equals(newPath);
        }
    }
} finally {
    try (Stream<Path> walk = Files.walk(zip1Path)) {
        walk.sorted(Comparator.reverseOrder())
                .forEach(path -> {
                    try {
                        Files.delete(path);
                    } catch (IOException e) {
                        throw new Error(e);
                    }
                });
    }
}
