In accordance with the Google Cloud Platform  deprecation policy, you will be able to migrate your projects off the Java 7  runtime over the next 12 months prior to the shutdown date of January 16, 2019.  For more information, see the   Java 7 runtime  deprecation page.     Please note the following incompatibilities between the Java 7 and Java 8  runtimes:     For a full list of Java 7 and Java 8 incompatibilities, please see this   guide.
