TLDR: The new updates are 1.8.0_411 (aka 8u411), 11.0.23, 17.0.11, 21.0.3, and 22.0.1 respectively). Crazy that there are now 5 current Java releases, I realize. More below, including more on each of them including what changed and the security fixes they each contain (including their CVE scores regarding urgency of concerns), offered in Oracle resources I list below. Oracle calls these updates "critical patch updates" (yep, CPU), but they are in fact scheduled quarterly updates, so that "critical" nomenclature may sometimes be a bit overstated. And as is generally the case with these Java updates, most of them have the same changes and fixes across the four JVM versions, though not always.

For some folks, that's all they need to hear. For others, read on.

As one of the premier conferences for both Adobe ColdFusion and Lucee, I highly recommend you attend the event if you can. Plus, if you don't live in Europe it's a great excuse to vacation on the continent and be tax-deductible at the same time! :-)

My talk this year (my 8th straight appearance at the event) will be a new one for me. Here are the details:

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 will be presenting presented a talk on this topic, online this Thursday, at noon US Eastern, on the CFMeetup youtube livestream (which will be was recorded). Folks who are members of the Online ColdFusion Meetup will already have gotten notification about this, but for those who are not, 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.

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.

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, you may want to read a more recent post I did on this matter, in October 2023.

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".

Read on for more, where I cover:

• Finding more info on this update
• A suggestion on blocking the _cfclient query string
• News for those doing manual offline installs: this update DOES have a zip
• As for doing a Java update along with this update
• CF2018 WAS indeed also updated
