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 :) On Mon, 25 Apr 2022 at 05:20, [email protected] <[email protected]> wrote: > > Yeah that would be the consequence. > > However I would recommend always using the latest JRE/JDK for > running/deploying OpenMeetings.
