Update: 3 days after this update, Adobe released yet another, and then 4 days after that they released yet another, both p1 security updates. While I have posts on each of the two subsequent updates, the one on Jul 14 and then the one on Jul 19, the information below is still important and has details that I do not repeat in the later post.

For more resources as well as some additional thoughts on the updates, read on.

TLDR; For some folks, the above may be all you need to hear: you may be dropping your coffee and donuts now to get the update applied. Still others will see this "huge post" and think, "crap, I don't have time for this". For you, skip to the bottom and its "concluding key points". You can then decide what you think you do or don't "need to know" and pick and choose from the sections as you like.

Finally, for those who prefer because of the importance of all this to be led more carefully through understanding things (in a way that's worked for the many people I have helped so far this week, and is far more than either Adobe or Hackernews has shared), please do read on.

As for CF2021, it gets updates into 2025, and the currently running pre-release of CF2023 is a great sign for the continued vitality of CF. But this looming deadline for CF2018 is a reminder that as the years roll on, we not only get new versions but we must say good-bye to old ones.

Wondering what you can do? or when CF2021 or CF2023 support will end also? And what's the difference between "core" and "extended" support Adobe sells? (The extended support plan does NOT provide updates beyond this coming July.) For more on these, including official Adobe documentation that discusses such things, as well as my thoughts on migration, costs, various options to consider, and more, do read on.

What if you want it back? In this post, I explain what changed, why, and how to get the functionality back--albeit at your own risk. For more, read on.

Update Jul 2023: Before considering what I share in this post, note that if you have updated your CF to use the Java update from Jul 2023, the cause of this error may be due to a totally different issue. See my post from July 2023 on that matter.

Update Feb 2023: In mid-February 2023, Adobe did re-sign their jars and placed them on the uploads site so that either the CF Admin update download or anyone performing a manual download after that date WOULD get the newly signed jars, and the problem below then no longer happens. (They are now signed as "SHA256withRSA, 4096-bit key".) I leave the rest here still for those who would want to understand what DID happen and why the update jars that were in place then DID change (slightly) for this reason.

TLDR: The new updates are 1.8.0_341, (aka 8u341), 11.0.16, 17.0.4, and 18.0.1 respectively). And as is generally the case with these Java updates, most of them have the same changes and fixes as each other (though not always).

Oracle calls them "critical patch updates" (yep, CPU), but they are scheduled quarterly updates, so take that "critical" nomenclature for what it is. For more on each of them, including what changed and the several security fixes they each contain (including their CVE scores regarding urgency of concerns), see the Oracle resources I list below. I also a bit more if you may be skipping to this from a JVM update from before Apr 2021, as well as info for Adobe ColdFusion users on where to find the updated Java versions, what JVM versions Adobe CF supports, and more.

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

• Finding more info on these Jul 2022 Java updates
• News for my CF audience (getting the Java updates from Adobe or Oracle, how to update, why you should NOT for now use Java 17, etc)
• Should you apply the update? how soon?
• Beware a change in the April 2021 JVM update, if you may be skipping over it
• Wrapping up, getting more help

Now in 8.7.7, which was released last week (Mar 1), the benefit of that feature has been extended so that a) the same information is written to both the FusionReactor request logs and b) it's also now available in FR crash protection alert emails. In this post, I'll show you examples of what's changed for each, and I'll note another related changes in the prior FR update, 8.7.6.
