Googles App Engine cloud has added official support for Java 11, the latest long-term support (LTS) version of the Java language platform, as a production release.
The App Engine Standard Environment Java 11 runtime is generally available for running any Java 11 application, web framework, or service in a managed serverless environment. Java 11 had been offered on App Engine in a beta release since June.
