GAE std java8 timeout exception logging?

[Robert Dyas]

With GAE std and java8, when the 60 second time limit is exceeded and your process is killed (or whatever) it does not appears that this timeout is shown in the logs? Am I missing something or is this a bug?

That does indeed sound like a bug as DeadlineExceededException should be raised when a request runs for over 60 seconds. If you are consistently seeing this behavior you should create an issue on our App Engine issue tracker so we can make the product team aware of it.
