Yes, the KAs need to be reviewed and updated to include 1902, but the requirement to remove that Java option is noted in the docs on this page. Easy to miss as you made the change after installing.

We have documented it here: Updating Java paths after upgrading Java - Documentation for Remedy Deployment 19.02 - BMC Documentation
Please follow and let us know in case you run into any issues.
Following up on these recommendations, as I stumbled upon Garbage First Garbage Collector Tuning and Garbage-First Garbage Collector Tuning mentioning to avoid -XX:NewRatio setting (among others) when using -XX:+UseG1GC.
I just installed 19.08 ARS and found the setting present in arserver.config so I was wondering wheter I should remove it or not.
Please can you advise?
Maybe -XX:NewRatio was meant for use alongside-XX:+UseConcMarkSweepGC and/or -XX:-UseParNewGC?
Or maybe it doesn't have that much impact so that I can ignore it?
Thanks in advance!

Has BMC (or anyone else out there) done any performance testing between Java 8 vs. Java 11 vs Java 12 (now supported with 19.08)? Using the same hardware/software stack and just changing out the version of Java used?

NewRatio parameter is not recommended with G1.
"Avoid limiting the young generation size to particular values by using options like -Xmn, -XX:NewRatio and others because the young generation size is the main means for G1 to allow it to meet the pause-time. Setting the young generation size to a single value overrides and practically disables pause-time control. "
