One thing I forgot to mention is that we cant write to a file by an app deployed on GAE. So I think logging should be disabled as "CachedOutStream.java" seems to be flushing out the cache to a temp file on the local file system. So if I remove that operation of writing to file(as it is not allowed on GAE), as I suppose its just used for logging purposes, would it create any problems in turn ?
