Oracle JRE / JDK

 Java 1.8

 Java 11

AdoptOpenJDK

 Java 8 (HotSpot)

 Java 11 (HotSpot)

Known issues:

• There's a known issue with some Java 11 versions and TLS 1.3. We recommend Java 11.0.8 or later. 
• Some Oracle Java versions have bugs that impact Confluence. You can't run Confluence on Java 1.8.0_25 and 1.8.0_31 (see JDK-8059299) or Java 1.8.0_45 (see JDK-8068400).
• Some AdoptOpenJDK versions have bugs that impact Confluence. We recommend version jdk8u202 (see CONFSERVER-58784).
• You can't run Confluence on the OPENJ9 JVM from AdoptOpenJDK. Use the HotSpot JVM. 
• We use AdoptOpenJDK 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.

Good to know:

• You don't need to install Java if you plan to use the installer to install Confluence, as a Java 11 JRE is bundled with Confluence (provided by AdoptOpenJDK).
• See Bundled Tomcat and Java versions to see which Java version was bundled with your Confluence version.
