Recordings and links for my presentations in Jan 2024, Dec 2023
But some people seem to notice when news is shared of a recording being made available, so here you go.:-) These are 4 sessions I've done in Jan 2024 and Dec 2023.

So I'll be presenting a talk on this topic, online this Thursday, at noon US Eastern, on the CFMeetup youtube livestream (which will be recorded). Folks who are members of the Online ColdFusion Meetup will have already gotten email notification about this, including the meeting URL, but for those who are not members here are the details:

And as important, if you may have skipped some Java updates before this one, there are some additional points to consider regarding some potentially important changes in updates you may be skipping.
In this post, I cover several topics in both those areas.

If you apply the update using the CF Admin and then find that CF starts but the Admin and your code fail, I cover that also, in the second section below.
For more, read on.
TLDR; If you've configured either CF2021's java home to use Java 11.0.20 or later, or CF2023's java home to use 17.0.8 or later, you may find that applying CF updates ia the Admin will fail. You can apply the update via the command line, adding a needed new jvm arg:
-Djdk.util.zip.disableZip64ExtraFieldValidation=true
(to be placed BEFORE the -jar arg) in the java -jar ... command, as I discuss more in the 5th bullet point below. (If I've lost you with that simple suggestion, read the rest here. And all may benefit reading what precedes that suggestion, for context. I also offer other suggestions and info.)
For more resources as well as some additional thoughts on the updates (including what security matter it entails as well as some lessons learned in applying the update--especially if you may update your Java to the JVM released last month), read on.
You will find that you can no longer INSTALL CF updates via the CF admin, if CF is using this new Java version. And even if the CF update is run from the command line, if using this newer Java version that also will fail. In either case, there is a new JVM argument that solved the problem, as I discuss below.
This is happening in CF2023, 2021, and 2018. (And this may continue to happen with future JVM updates, until Adobe otherwise addresses the problem.)
As an update, this issue was finally fixed with the Oct 2023 CF update, CF2021 u11 and CF2023 u5--as long as it was applied before applying any later ones, it seems. Still, some may want to read on for context, or read a subsequent post I did on this matter in October 2023, and another in my discussion of the Nov 2023 cf update.As an another update, when I first created this post originally on July 21st, another problem was that you would find that you could no longer use the CF Administrator to download CF updates, if CF was running this new Java version. You would get an error reporting, "Failed Signature verification"--or in some cases you may see only "error failed". But within a couple of weeks, I found that the CF Admin COULD now download updates (including the August 2023 CF update) but the CF update STILL fails to install correctly, as discussed in this post, unless the workaround offered is used.
FWIW, Adobe has also updated the technotes for CF2021 update 10 and CF2023 update 4 with a text box at the top that acknowledges this issue and points to this post for more detail.
In this post, I explain a) what this is all about, then b) how you can fix the problem of INSTALLING the update using the CF Admin, I'll explain how it seems we HAVE to workaround that problem (for now). I also offer a link to a bug report I've filed. I even offer a thought on how this new JVM update may prove over time to affect MORE than just this, and even MORE than just CF (and Lucee) but many java apps. Read on for more.
Yes, this is shocking. Yes, unless there's a good explanation, I can understand how many would feel "someone on the CF team should be flogged". Don't shoot me: I'm just the messenger. I don't work for Adobe.
But I will add that in this post, besides just sharing news about the update (and more than JUST pointing to the update), I also offer an ADDITIONAL "fix" some will want to consider, to go BEYOND what this update addresses. See the discussion on "blocking the _cfclient query string".
