Recently while working with HttpClient for accessing 3rd party service (CURL Service) in Java application, I came across problem like:

javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
....

I got this problem in JDK 7. With some research on this problem I found 2 suggestions i.e.

• Add certificate of that particular 3rd party in your JDK 7 Truststore. [Which I tried but still got same issue]
• Use JDK 8 instead of JDK 7 [Which I tried and it worked for me]

So I am trying to understand like how SSL Handshaking takes place in Java 8 as compare to Java 7 or lower? And I can fix this issue in JDK7

Code Snnipet

public String getProduct(final String accessToken) throws IOException, ParseException {

    log.info("accessToken: " + accessToken);
    final String stringUrl = "https://api.molt.in/v1/products";
    HttpClient httpClient = HttpClientBuilder.create().build();
    HttpGet getRequest = new HttpGet(stringUrl);
    getRequest.setHeader("Authorization", "Bearer " + accessToken);
    HttpContext httpContext = new BasicHttpContext();
    HttpResponse response = httpClient.execute(getRequest, httpContext);
    log.info("Response Code : " + response.getStatusLine().getStatusCode());

    BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
    StringBuffer result = new StringBuffer();
    String line = "";
    while ((line = rd.readLine()) != null) {
        result.append(line);
    }
    log.info("result: " + result);

    rd.close();
    return result.toString();
}
