Different secret keys with 192 and 256 length

Question

Hello everybody
I have this problem.
I want to generate secret key from my password. I used this code:
String algorithm = "PBEWITHSHA1AND192BITAES-CBC-BC";
    int iterations = 3456;
    byte [] salt = Hex.decode("20CB84A0CE6F4C5B");
    String pass = "321TestovacieHeslo";
    byte [] passBytes = pass.getBytes("UTF-16BE");
    //1.way
    PKCS12ParametersGenerator gen = new PKCS12ParametersGenerator(new SHA1Digest());
    byte [] testBytes = PKCS5S2ParametersGenerator.PKCS12PasswordToBytes(pass.toCharArray());
    gen.init(testBytes,salt,iterations);
    //gen2.init(testBytes,salt,iterations);
    KeyParameter parameter =
        (KeyParameter)gen.generateDerivedParameters(192);
    //2.way
    SecretKeyFactory keyFact = SecretKeyFactory.getInstance(algorithm);
    SecretKey key = keyFact.generateSecret(
            new PBEKeySpec(pass.toCharArray(), salt, iterations, 192));
    //print
    byte [] output = key.getEncoded();
    byte [] output2 = parameter.getKey(); Both ways give me same results, but now I wanted to achieve same password as from Crypto++.
This code give same result with 128 bit keys but not with 192 ot 256 bit. (I tried 8/16/24 byte salts)
Where is problem ? Padding ? Because when I used all same parameter with 128 and 192 bit I got these results:
128bit:7b4b7b59b230003f452fa4fe7c0eb9c1
192bit:7b4b7b59b230003f452fa4fe7c0eb9c19231f5a471741535
My concret case:
input: password: "321TestovacieHeslo"
salt:"20CB84A0CE6F4C5B"
iter:3456
And I need this 24 byte larger key from Crypto++:
C6408B48D17A1A38F51AC7F05DE24CBB967049DF9FDDCB8F
but I got this:
1eb4b95846cdfb60eae519c8efa2569011e30e964be7cfbd
Can anybody help me ?
Thanks
