Java 11 Apache HTTPClient SSL certificate authentication not working

I am using modified version below code for SSL client certificate authentication. It worked in JDK 8, recently I changed to JDK 11, now with same code authentication is failing. If I switch to JDK 8 it works. Any changes in JDK 11 to handle the SSL client certificate authentication? Any tips to make this code work JDK will be helpful.
