Getting SSLException: fatal warning received: internal_error on startup on Tomcat 7, but works fine with the main Java 7 method

When I run this code in the main Java method, I get Status = 200, which is good.

try {
    String url = "https://www.celltowerleaseexperts.com/"; 
    int status = HttpResponseUtil.getResponseCode(url);
    logger.warn("Status = " + status);
} catch (Exception e) {
    logger.warn(e.getMessage(), e);
}

This is the code for HttpResponseUtil:

import java.io.IOException;
import java.security.KeyManagementException;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;

import javax.net.ssl.SSLContext;

import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.conn.ssl.NoopHostnameVerifier;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.TrustSelfSignedStrategy;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.ssl.SSLContexts;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class HttpResponseUtil {

 private static final Logger logger = LoggerFactory.getLogger(HttpResponseUtil.class);

 private final static String USER_AGENT = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0";

 public static int getResponseCode(String url) throws IOException {

  SSLConnectionSocketFactory sslsf = null;
  try {
   SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(new TrustSelfSignedStrategy()).build();
   sslsf = new SSLConnectionSocketFactory(sslContext, NoopHostnameVerifier.INSTANCE);
  } catch (KeyManagementException | NoSuchAlgorithmException | KeyStoreException e) {
   logger.warn("Using SSLContexts.createSystemDefault()");
   SSLContext sslContext = SSLContexts.createSystemDefault();
   sslsf = new SSLConnectionSocketFactory(sslContext, NoopHostnameVerifier.INSTANCE);
  }

  CloseableHttpClient httpClient = HttpClients.custom()
    .setUserAgent(USER_AGENT)
    .disableAutomaticRetries()
    .disableCookieManagement()
    .setSSLSocketFactory(sslsf).build();

  try {
   HttpGet httpGet = new HttpGet(url);
   CloseableHttpResponse response = httpClient.execute(httpGet);
   return response.getStatusLine().getStatusCode();
  } finally {
   httpClient.close(); 
  }
 }

But when I try to run it on Tomcat, I got this error:

I am using Java 7 and Apache Tomcat 7.0.59

***** EDIT **: I turned on jvax.ssl log output as suggested by Sangram Jadhav. Here it is: (too long to include here, so I just put it in an online notebook)

This may be due to a problem in JDK8. Problem

JDK/JRE JDK/JRE. , JDK/JRE 1.8.0_91.

Edit:
