The problem is resolved. We were trying to (1) read some POSTed data,
(2) converting it and then (3) POSTing it again.
setting the HttpServletRequest.setCharacterEncoding("UTF-8") before
(1) solved the issue.
But this brings us to two more questions.
1. Even when the setCharacterEncoding() was not set, the payload in
(1) has the encoding set to UTF-8 already. Why, then, was the encoding
not used by the app engine by default?
2. How does one set the default encoding for the jvm instance in app
engine?
