Summary

As stated in our Supported Platforms documentation; Confluence supports Oracle JRE/JDK and Eclipse Temurin (previously AdoptOpenJDK) as valid Java environments. 

Both vendor/provider frequently release new versions of the Java SE Runtime Environment, which include performance improvements and/or bug fixes. Being up to date with the latest JDK version will help Confluence and other Java-based applications run smoothly and more stable. Atlassian strongly recommends keeping your JDK updated to the latest supported JDKL version for Confluence version.

Environment

Confluence Data Center 8.X and later

Solution

The latest releases and bugs fixes on JDK side will depend on the vendor/provider used: 

  • For Eclipse Temurin OpenJDK released by Adoptium, please see the OpenJDK Archives Download Page.
    • Atlassian uses Temurin distribution to replicate issues raised with OpenJDK. If you’re using a different distribution of OpenJDK we’ll still provide support for our products. However, if the bug is caused by a problem in Java distribution, you'll need to contact the Java distributor for help. We suggest you use this distribution unless needed otherwise.
  • For Oracle JDK, you can check their latest JDK versions in Java Downloads site; and previous versions in Java Archive. Please check Oracle's licensing for usage details.


If you need additional help while upgrading your JDK, please review our documentation about it:
