Installing Java

Jump to Section

OpenJDK 22 was released on 3/19/2024 and is not compatible with version 3.4 or older of the Intelligence Hub. Trying to use this v22 will result in an exception on startup. Downgrade to version 21 to avoid this issue. This issue will be resolved in a future release.

Java Runtime Environment is required to run HighByte Intelligence Hub.
