Weird RMIR behaviour - 2 Roku upgrades

Yes. I was getting confused by Mark continuing to mention Java Control Panel and Update Now. Update Now will never update to anything beyond Java 8. It is not an error, it is simply obsolete.

Because Oracle changed everything from Java 9 onward, including any links such as "Update now".
"Update now" DOES NOT WORK ANY LONGER. Ignore it and install Java 24. It is a jdk, there are no more separate runtime versions.

Well, I'm confused because I keep being told to update to JDK 24 which I have - more than once - yet also being told that doing so would update my "obsolete" JRE 8, which obviously it has not.

You are up to date with Java, Mark, you issue lies elsewhere.

Thank you for the clarification. I kept chasing this only because I thought I needed to test with Java 9 and that the only way to do so was by installing the entire JDK.

I don't know what you were expecting to happen with "updating your obsolete JRE 8". It clearly HAS been updated as RMIR now shows you are using Java 24. Perhaps you don't realize that you can have several versions of Java on your machine at the same time. I have jdk1.8.0_221 (Java 8), jdk14.0.2 (Java 14) and jdk24.0.1 (Java 24) on mine. On an earlier machine I had Java 6, Java 7 and Java 8 so this is not a new feature. The one in use at any time is determined by the Environment Variables, in particular Path and JAVA_HOME. Hope this helps.

I uninstalled 8 after I installed 24. Is that not recommended?

It is neither recommended nor not recommended, it is simply unnecessary and of no significance. Multiple Java versions can exist simultaneously, they do not interfere with one another. You can uninstall one you never intend to use again if you wish, but you do not need to do so.
