That bug report (https://github.com/spring-projects/spring-boot/issues/9615) is
*for* version 1.5.4. I believe you'll find it fixed in subsequent versions of
Spring Boot.
See the following project for a working sample app:
https://github.com/GoogleCloudPlatform/getting-started-java/tree/master/appengine-standard-java8/springboot-appengine-standard
It's using 1.5.7.RELEASE.
