Issue

• The application running on EAP needs to establish an HTTPS connection to another application.
• While trying to establish the HTTPS connection we are getting a ClassCastException in one of our application server while in the other server, the HTTPS connection works perfectly fine.
• Same code is deployed in both application servers.
• Provided below is an extract of the code:

HttpsURLConnection con = null;
URL url = new URL("https://host:port/resource");
try {
SSLContext ssl_ctx = SSLContext.getInstance("TLS");
TrustManager[] trust_mgr = get_trust_mgr();
ssl_ctx.init(null, trust_mgr, new SecureRandom()); 
HttpsURLConnection.setDefaultSSLSocketFactory(ssl_ctx.getSocketFactory());
con = (HttpsURLConnection) url.openConnection();//Exception thrown here

Exception detail:

java.lang.ClassCastException: com.sun.net.ssl.internal.www.protocol.https.HttpsURLConnectionOldImpl cannot be cast to javax.net.ssl.HttpsURLConnection
