It works on an empty project. So I compared my project with empty project. The difference is my project uses Maven.
I realized gwt-servlet.jar was missing in my project. So when I copied the gwt-servlet.jar in the lib folder created inside WEB-INF it worked! But the funny thing is my RPC call with String object was working fine without gwt-servlet.jar Thanks everyone on contributing and helping me. I am still surprise how did gwt-servlet.jar gets deleted or may not be there in the first place. And how did simple RPC worked before with String objects and not working with ArrayList or HashSet objects. We learn new things every day! Thanks again all of you for taking your time to guide me here. I appreciate it!
