Best Java version for ACS

[Dan Bale <dan.bale@xxxxxxxxxxxxxxxxxxxxx>]

I'm having problems using some facets of ACS 1.1.9.5.  The problems are not new to that version, but that's what I'm currently using.  The biggest issue is that using ***multi-tab*** green screens randomly changes the window size, sometimes to double the size of my monitor, other times to 2" x 3" window.  Another issue is ACS crashing or locking up if I have too many windows/sessions open.  (No judgement! We manage 30 partitions here.)  ACS "About" says:
> java.version: 17.0.9
> java.vendor: Eclipse Adoptium
> java.home: C:\Program Files (x86)\Eclipse Adoptium\jre-17.0.9.9-hotspot
(Adoptium is our company's current standard to replace Oracle.)
IBM support wants me to use Java 11 which, if I understand Java versioning correctly, seems like a downgrade.  They are specifically recommending IBM OpenJ9's Java 11, which is at least 3 years old.  Their download site shows OpenJ9 Java 21 LTS.  Not knowing how much longer IBM will support version 11 (LTS), I'm wondering if anyone is using a version of OpenJ9 Java newer than version 11 and not having problems with ACS.
