IllegalArgumentException: IV buffer too short for given offset/length combination

问题

I have one application which is in PHP encrypting text using openssl_encrypt with following method. (Using same value for salt and iv as '239422ae7940144f')

function encrypt_password($password) {
    define('AES_256_CBC', 'aes-256-cbc');
    $sessionId = $password;
    //random number for encrtyption(salt)
    $salt = '239422ae7940144f';
    $iv = $salt; //cipher length
    $encryptedSession = openssl_encrypt($sessionId, AES_256_CBC, $salt, 0, $iv);
    return array('encryptedPassword' => $encryptedSession, 'salt' => $salt);
}

function decrypt_password($result) {
    define('AES_256_CBC', 'aes-256-cbc');
    $vPassword = 'xUP9PwhcXm5xbKIfiSxMCA==';
    //random number for descrypt(salt)
    $salt = '239422ae7940144f';
    $iv = $salt; //cipher length.
    $decrypted = openssl_decrypt($vPassword, AES_256_CBC, $salt, 0, $iv);
    return $decrypted;
}

Encrypt of password 'abc123' provides 'xUP9PwhcXm5xbKIfiSxMCA==' and decrypting it gives back 'abc123'.

How to find equivalent java program which would do the same. I tried using the example on Using Java to decrypt openssl aes-256-cbc using provided key and iv, but it fails with

java.lang.IllegalArgumentException: IV buffer too short for given offset/length combination.

Following are the secretKey and initVector lines in java program I am using.

    final byte[] secretKey = javax.xml.bind.DatatypeConverter.parseHexBinary("239422ae7940144f");
    final byte[] initVector = javax.xml.bind.DatatypeConverter.parseHexBinary("239422ae7940144f");
