OM to JDK17 ?
Hi,
does this change:
https://github.com/apache/openmeetings/commit/abeef2dfa6b80aabd26c19460745e60837102356
Mean that we can update the compile time requirement from JDK11 to JDK17 ?
Thanks!

Also please make sure that it will function properly on iOS and macOS

Re: OM to JDK17 ?
Posted by "seba.wagner@gmail.com" <se...@gmail.com>.
No quite. Maxim suggests:
v6.3.0 would be released to be compatible with compiling with JDK17 but the
source code level would still be Java11. So that the compiler generates
Java11 compatible bytecode. So you can run v6.3.0 with JDK11/JRE11 (however
later JRE versions will improve performance)
v.7.0.0 would be compiled with JDK17 *and* the source code level would be
updated to Java17 and the generated bytecode would be Java17. Which would
require a JRE17 to run the code later.
Thats how I understood the proposal at least.
Thanks

Sounds good
Would moving to JDK17 be a quick follow up release of v7.0.0 ?

Re: OM to JDK17 ?
Posted by Maxim Solodovnik <so...@gmail.com>.
Hello Seb, Alvaro :)
from now on OM can be compiled with JDK17
Resulting jars should be java11 compatible
we might switch to jdk17 in next major version
OM should work as expected under JRE17 and this version is more performant
I'll try to review open JIRAs and fix some minor and urgent ones
So we can perform 6.3.0 release :)

Re: OM to JDK17 ?
Posted by "seba.wagner@gmail.com" <se...@gmail.com>.
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:
https://advancedweb.hu/a-categorized-list-of-all-java-and-jvm-features-since-jdk-8-to-17
It is hard to say which ones may have the biggest effect on running
OpenMeetings/Tomcat/Wicket.
