Hi Ceki, I considered the possibility of writing a wrapper on my own. But first I would appreciate your advice if that would actually be a reasonable approach. Maybe I am missing something and trying to solve it on the wrong way?
One possibility would be a wrapper that is very similar to your JDK14LoggerAdapter, reusing Appengine's JUL implementation. Another possibility would be a wrapper that calls Appengine API directly, but I am not sure if this is possible. I will do some research and prototyping and let you know if succeeded or not.
