coldfusion 2021 update 4: no directory for update 4, use the current Java or bundled Java

Michael, I know you are working directly with Adobe support now, but going back to your first message, you say the update failed--but the log you showed indicates that it worked, with zero errors. What led you to feel it had failed?

Also, as for the docs suggesting you use the jvm cf came with (when doing the command line update), the point there is more to keep people from running it with a JVM that Cf does not support. Since cf2021 currently supports Java 11 only, that would mean any other later or earlier jvm one might have installed.

To be clear, as long as the jvm you use is 11, it doesn't matter where it's installed or if cf is using that EXACT one.

As for the confusion over the manual steps since update 2, and the whole packages url thing, that is indeed unfortunate and Adobe could considerably improve the technote discussion of that.

Finally, to your last question in the first note: "as of update 3, is CF2021 now able to function with a current version of Java and have sandbox security enabled?"

First, no cf update for cf2021 has changed anything about the jvm version supported: it's only Java 11. Perhaps the next update could add support for the newest LTS Java version, 17. Only time will tell.

But you seem to be suggesting that some Java version kept cf from working with the cf sandbox feature. I'm not aware of any such connection. I will say that recent Java versions are marking the java security manager feature as "deprecated", and the sandbox feature does rely on that. So SOME day the sandbox feature will no longer work with some future jvm version (some are speculating Java 21, the next LTS release, due Sept 2023). Again, only time will tell. I sure hope Adobe is attending to that potentiality.

Hope something above is helpful. 

If you may see this only after you meet with Adobe and perhaps you solve things, I hope you'll be sure to offer an update, even if only in that thread with Ravi. But either way, if you could confirm you see this and what I've shared (especially on these other matters you raised), it would be appreciated. 

You need to run the update with the java that ColdFusion is using, if your ColdFusion is pointed to java which is installed in the Program Files directory, you need to run the update using that Java.

If you do not have internet connectivity then you need to follow the manual steps for applying the update.

Let us know whether you have launched Command prompt as admin, also can you share the Coldfusion update log while applying the update
