The java client code is available at https://github.com/shivchelwa/elastic-ssl-client. Please advice if any correction required in this case.

I got it fixed. The truststore password was blank and I have to use below peace of code to load certificates from truststore.

    KeyStore truststore = KeyStore.getInstance("pkcs12");
    truststore.load(is, "".toCharArray());

But, I am not able to use Basic Authentication with HTTPS. I am use default "native" realm. Is Basic Authentication not supported when HTTPS is enabled and realm is "native"?
