Yeah that would be the consequence.

However I would recommend always using the latest JRE/JDK for
running/deploying OpenMeetings. There is no advantage of using JDK11.

Later Java versions provide performance optimisations that are not
available in older versions. Most of them also require code changes, but
some don't.

You can read about some performance gains by simply switching to JRE/JDK17
here:
https://www.optaplanner.org/blog/2021/09/15/HowMuchFasterIsJava17.html

Above article mostly compares the Java Garbage Collection process GC. And
it calculates a 8.66% performance gain by simply running the same code in
JDK17 without any code changes.
However you can achieve even higher performance gains by additionally using
newer language features.

You can also some list of improvements (including performance ones) across
different Java versions here:

It is hard to say which ones may have the biggest effect on running
OpenMeetings/Tomcat/Wicket.
