Have you changed your code recently, or has this exception started popping without any code changes? If you have changed your code, can you look in your codebase/libraries for duplicate copies of the Guava/google-collections library?

I did check what you mentioned... but i haven't duplicate copies of  Guava library

This sort of programming/development question would be better directed to Stack Overflow's App Engine tag. I recommend posting there for more technical issues as it is more likely that you will get a solution to your problem.
