ZipFileStore#supportsFileAttributeView(String) doesn't throw NPE

[Andrey Turbanov]

Hello.
I've noticed that ZipFileStore#supportsFileAttributeView(String)
doesn't throw NullPointerException when 'null' is passed as an
argument.

public boolean supportsFileAttributeView(String name) {
    return "basic".equals(name) || "zip".equals(name) ||
           (("owner".equals(name) || "posix".equals(name)) && zfs.supportPosix);
}

Method body was changed to not throw NPE in JDK-8213031.
I wonder if it was an intentional change or not?


My reproducer shows difference between ZipFileStore and WindowsFileStore

public static void main(String[] args) throws IOException {
    checkFsForNull(FileSystems.newFileSystem(Path.of("D:\\config.zip")));
    checkFsForNull(FileSystems.getDefault());
}

private static void checkFsForNull(FileSystem fs) {
    
fs.getFileStores().iterator().next().supportsFileAttributeView((String)null);
}
