The Memcache service is currently not available for the App Engine flexible environment, as mentioned in the "Upgrading to the Latest App Engine Flexible Environment Beta Release" document <https://cloud.google.com/appengine/docs/flexible/java/upgrading>. If your code contains calls to memcache, errors are to be expected, as seen in your attached screen capture. If you need access to a memcache service immediately, you can use the third party memcache service from Redis Labs.
Jetty's default behavior assumes presence of the slf4j facade in your system. If slf4j is present in your classpath, it will emit logging events to slf4j to handle, using the Slf4jLog handler. This does not seem to happen in your case, and the behavior observed corresponds more likely to a fallback to StdErrLog, emitting to System.err. More details on Jetty logging may be found in the "How to enable logging in jetty?" entry <http://stackoverflow.com/questions/25786592/how-to-enable-logging-in-jetty> from Stackoverflow. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
