Adobe Experience Manager 6.5 and JDK11 by INITIALYZE

Abstract

We recently switched to Java 11 with Adobe Experience Manager 6.5 for some of our customers and ran into several issues especially with environment stability. This post outlines some of the items you need to be aware of and address when using Java 11 with Adobe Experience Manager.

I’ve organized this post into a short version and a long version. If you’ve already done all the work of updating your pom, dependencies, compiler, plugins, to work with Java 11 but, having environment issues only, the Short version below outlines quick steps that you can take to ensure your Adobe Experience Manager instance is stable after builds and deploys.

The Longer version in this article walks through all the things you need to take care of when using Java 11 with Adobe Experience Manager in more detail.
