FileDataStoreFactory method setPermissionsToOwnerOnly only supports Unix

[rbeede]

com.google.api.client.util.store.FileDataStoreFactory

setPermissionsToOwnerOnly does not use newer Java 7 or 8 APIs for setting file/dir ownership and thus generates spurious warnings like "com.google.api.client.util.store.FileDataStoreFactory setPermissionsToOwnerOnly
WARNING: unable to change permissions for everybody: "

The code only takes into account file systems as seen on Unix-like OSes that use a simple mode for the permissions. Windows file systems have ACLs and require different API calls to modify ownership and permissions. The latest Java APIs should be used instead which can handle both file system types.

This warning occurs for anyone using the Drive API SDK samples and causes confusion for new developers using the API.

Temporary workaround:

        final java.util.logging.Logger buggyLogger = java.util.logging.Logger.getLogger(FileDataStoreFactory.class.getName());
        buggyLogger.setLevel(java.util.logging.Level.SEVERE);

I believe this issue is causing downstream issues with Windows users.

I'm not sure though.

        buggyLogger.setLevel(java.util.logging.Level.SEVERE);

where should I put this code？
`public class Auth {

    // Load client secrets.
    Reader clientSecretReader = new InputStreamReader(Auth.class.getResourceAsStream("/client_secrets.json"));
    GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, clientSecretReader);

    // Checks that the defaults have been replaced (Default = "Enter X here").
    if (clientSecrets.getDetails().getClientId().startsWith("Enter")
            || clientSecrets.getDetails().getClientSecret().startsWith("Enter ")) {

        System.exit(1);
    }
