2. Proceed through the steps, until you reach the step when the J2SDK directory is specified, ensure that the path is pointing to the proper: jdk-11.0.11+9 folder

Environment

Release : 16.0.0

Component : Clarity Install and Upgrade

Resolution

Fixed in 16.0.1 as DE63068

Workaround:

1. Delete the file: $install16.0.0/upgrade/release-overrides/15.9.3/preexecute/setup-props.xml
2. Reopen the command prompt and start the upgrade again

Alternatively, you can just ignore the warning and continue with the install with the current, correct JDK value for JDK 11. The upgrade will not be affected.
