Solution :

I had this issue due to my operating system, it is different to different platforms , its all about JRE implementation.

        new SecureRandom(key.getBytes())

will give the value in Windows, But it is different in Linux. So in Linux you need to change it to

        SecureRandom secureRandom = SecureRandom.getInstance("SHA1PRNG");
        kgen.init(128, secureRandom);
