JAVA aes加解密在mac中的问题

现象描述：

windows上加解密正常，MAC上加密正常，解密时发生如下异常：

javax.crypto.BadPaddingException: Given final block not properly padded

at com.sun.crypto.provider.SunJCE_f.b(DashoA13*..)

at com.sun.crypto.provider.SunJCE_f.b(DashoA13*..)

at com.sun.crypto.provider.AESCipher.engineDoFinal(DashoA13*..)

at javax.crypto.Cipher.doFinal(DashoA13*..)

解决后代码如下：

KeyGenerator keyGen = KeyGenerator.getInstance("AES");

String pwd = "passord";
SecureRandom random=SecureRandom.getInstance("SHA1PRNG");
random.setSeed(pwd.getBytes());
keyGen.init(128, random);
SecretKey skey = keyGen.generateKey();
byte[] raw = skey.getEncoded();

SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
