Issue while upgrading from JDK-8 to JDK-11 in JIRA Server plugin

Hello Developers,
I need your help. I am a Software Engineer. Our team develops a plugin on the JIRA Server(Jira version: 8.3.0). We want to upgrade our JDK from 8 to 11.

But according to this article,

Jira provides support to JDK 8 & 11 both. But JDK 11 features are not supported. I am unable to understand this.

Could you please tell me what I need to do if I want to use JDK 11 anyhow in my development? Could you please help me with this? What do I need to do if I want to deploy my Java 11 JAR over the JIRA Server?

Regards,
Heli

I would also like to have an answer to this question. +1

You can’t. Java 11 code does not run on Java 8 JVM. Stay with Java 8 until Atlassian stops supporting Java 8.

Why should we wait for Atlassian to stop support for Java 8 if they already have support for Java 11? Would waiting not be leaving it too late? Also, can the development not happen for both 8 and 11 concurrently?
