Java 11 End of Support in App Engine: Exact Date and Post-Support Options?

[MarcusKim]

According to the document below, the end of support for Java 11 in App Engine will end in October.
Does anyone know the exact date?

We don't have time to upgrade our app to Java 17.
Is there a way to use all activities such as app upgrades and deployments without any problems even after support ends?

According to the document below, it seems possible to apply organizational policies, but this only applies to Java 8. Does this also apply to Java 11, which has been terminated since October?

Hi @MarcusKim,

Welcome to Google Cloud Community!

Regarding the exact end of support (EOS) date for Java 11 runtime in App Engine, there is no specific date as of now other than the provided date in runtime support schedule which is in October 2024. 

When a runtime reaches the end of support date, your application will continue to run and receive traffic, but you will no longer be able to create and/or update the application on that runtime.

As of now, the only supported runtime for enabling deployments or applying policies reaching EOS are the first-generation runtimes such as Python 2.7, Java 8, PHP 5.5, and Go 1.11. For other runtimes like Java 11, you may try to file a bug for an exception, but it will be on a case-by-case basis and note that I won’t be able to provide a date as to when this will be handled.

I hope the above information is helpful.
