Java アプリケーションでファイルをアップロードするために Dropbox Java API を使用しようとしています。どういうわけか、解決できない同じ SSL エラーが発生します。助言がありますか？

このコードを使用しました (http://aaka.sh/patel/2011/12/20/authenticating-dropbox-java-api/)

    public class DropboxTest {

    // App key & secret that Dropbox's developer website gives your app
    private static final String APP_KEY = "myAppKey";
    private static final String APP_SECRET = "myAppSecret";
    // Define AccessType for DropboxAPI object
    final static private AccessType ACCESS_TYPE = AccessType.APP_FOLDER;
    private static DropboxAPI<WebAuthSession> mDBApi;

    public static void main(String[] args) throws Exception{

        // Initialize the goods/session
        AppKeyPair appKeys = new AppKeyPair(APP_KEY, APP_SECRET);
        WebAuthSession session = new WebAuthSession(appKeys, ACCESS_TYPE);

        // Initialize DropboxAPI object
        mDBApi = new DropboxAPI<WebAuthSession>(session);

        // Get ready for user input
        Scanner input = new Scanner(System.in);

        // Open file that stores tokens, MUST exist as a blank file
        File tokensFile = new File("TOKENS");

        System.out.println("Enter 'a' to authenticate, or 't' to test reauthentication: ");
        String command = input.next();

        if(command.equals("a")){

            try {

                // Present user with URL to allow app access to Dropbox account on
                System.out.println("Please go to this URL and hit \"Allow\": " + mDBApi.getSession().getAuthInfo().url);
                AccessTokenPair tokenPair = mDBApi.getSession().getAccessTokenPair();

                // Wait for user to Allow app in browser
                System.out.println("Finished allowing?  Enter 'next' if so: ");
                if(input.next().equals("next")){
                    RequestTokenPair tokens = new RequestTokenPair(tokenPair.key, tokenPair.secret);
                    mDBApi.getSession().retrieveWebAccessToken(tokens);
                    PrintWriter tokenWriter = new PrintWriter(tokensFile);
                    tokenWriter.println(session.getAccessTokenPair().key);
                    tokenWriter.println(session.getAccessTokenPair().secret);
                    tokenWriter.close();
                    System.out.println("Authentication Successful!");

                }

            } catch (DropboxException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }

        else if(command.equals("t")){

            Scanner tokenScanner = new Scanner(tokensFile);       // Initiate Scanner to read tokens from TOKEN file
            String ACCESS_TOKEN_KEY = tokenScanner.nextLine();    // Read key
            String ACCESS_TOKEN_SECRET = tokenScanner.nextLine(); // Read secret
            tokenScanner.close(); //Close Scanner 

            //Re-auth
            AccessTokenPair reAuthTokens = new AccessTokenPair(ACCESS_TOKEN_KEY, ACCESS_TOKEN_SECRET);
            mDBApi.getSession().setAccessTokenPair(reAuthTokens);
            System.out.println("Re-authentication Sucessful!");

            //Run test command
            System.out.println("Hello there, " + mDBApi.accountInfo().displayName);

        }
    }
}

SSL 例外で終了します。

理解した。OSXでOpenJDKを使用していました。デバッグのためにJVMを-Djavax.net.debug=ssl実行したところ、ルート例外が発生しました

java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty

いくつかの調査の後、ここで解決策を見つけました： http://architecturalatrocities.com/post/19073788679/fixing-the-trustanchors-problem-when-running-openjdk-7

今はうまくいきます！
