Dear all,

I have developed an application in GWT that is running on GAE and I am receiving sporadic error like the one that I have reported in this post.

The problem is that from the stack trace I cannot figure out which is the cause (there is no my own code as you can see): please could you help me understanding how to solve the problem?

Thank you very much and best Regards,

Marco.
