Tomcat8 is running but not loading the page - ubuntu-16.04

Question

I had created a new host on the Digital Ocean to host my application. I have installed Tomcat8 and Apache but Tomcat8 is not responding when I try to curl for 8080 port. It just loads and loads but nothing happens.
The host is running on Ubuntu 16.04LTS OS.
This is the Catalina log file

Answer 1

After few hours of debugging, I have restarted the container reinstall Java JDK 8 and that seemed to fixed the problem.
