Hi Christopher, Thanks for the reply. I am using Tomcat6 and Velocity 1.6 As I mentioned I know this problem is due to the mapping I added to Spring context xml for Velocity engine bean, SimpleMailMessage, JavaMailSender because if I take it out from the xml, web application gets initialized in the expected manner. I did one more exercise for this problem. My web application being a larger and complicated web application, Spring context xml has mapping for lot of beans. So I creates an independent sample web application with Spring MVC and tried to implement the email sending with velocity template. It worked fine but when I merged it with my web original application, it started throwing the same ConcurrentModificationException exception. I have no clue what is causing this problem.
