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 suggested, 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.

It's been on my site as my "CFUpdate" page (linked to from my old-school top-level nav bar), and I've kept the page updated. [Hey, updating my meta resource on updates. That's SO meta!]

But I suspect a lot of people may never find it for one reason or another, so I wanted to offer a link to it here.

Check it out, and I welcome comments or feedback here.

I'll be offering my traditional "Hidden Gems in ColdFusion 2023" talk.

And see the conference web site for other speakers and their Summit sessions (with more to come).

Besides just being a great conference (in terms of content as well as meeting fellow attendees, Adobe folks, and vendors), which is being offered in-person only and at a VERY reasonable price of only US$199, the Summit is also a great chance for folks to pursue Adobe CF Certification (offered both online and in a separate one-day workshop the day after the conference, Oct 4, for just $100 more).

Note also that qualified students can attend the Summit for free. That's a great nod to Adobe supporting CF in higher education and among emerging developers.
