Thank you william for your suggestion. I was able to solve the bug temporarily by commenting the servlet mapping of the remote service class (which is a GWT module) in web.xml.

I am able to start the tomcat without the above bug after performing the following actions randomly, but i couldn't find the exact solution for this problem
1. Clean the tomcat or
2. Replace the existing tomcat configuration in eclipse with new one or
3. Switching over to another workspace or
4. Restarting the eclipse or the system.

It would be helpful for me if someone tells the exact problem and its solution since i get this bug frequently (2 to 3 days once).

I need to check the number of objects created by this java program.

class Test{

public static void main(String args[]){
System.out.println("Hello World !");
}

}
