Thanks all for the advice. From my experience, using a high version JDK environment for a standalone server in an enterprise isn't a blocker point. The user could use docker image or install a separate JDK like Trino. Please tell me if there are any blocking points! I will start to upgrade in 7.16 if there are no objections.
