What is the optimal Java version for Jira Data Center 9.4.6?

Jeramy

Recently we upgraded our Jira Data Center to 9.4.6. During the upgrade, I noticed that we are running Java 1.8. If I understand it correctly, this is the same as Java 8. I believe Java is up to version 17 (LTS) and 20. 

We are looking at upgrading our Java on our Jira DC VMs, but were wondering what is the best/optimized version of Java to run on Windows VMs hosted in MS Azure?

Hello @Jeramy 

 

Yes that is correct. Java 8 is Java 1.8, where 8 is the version number, and 1.8 is the version string. These versioning names are clarified in Oracle's article, Java Platform, Standard Edition 8 Names and Versions: In JDK 8 and JRE 8, the version strings are 1.8 and 1.8.

 

As a best practice, Atlassian recommends using the latest version of Java.

Jira 9.4

Jira	Tomcat	Bundled JRE	Tested JREs
9.4.6	Application Server Apache Tomcat/9.0.73	Adopt OpenJDK 11.0.13+8	-

 It looks like Java 17 is supported on 9.4.6 and Java 20 is not yet
