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.

As for my session, it will be "Transitioning to Java 17 from 11 or 8 for Admins":

You can learn more (in brief) about what's new in the bullets for 9.2.0 offered at the release notes page.

TLDR: For some folks, news of the new version is all the need to hear. For those who may like to hear a bit more about the update, read on.

TLDR: The new updates are 1.8.0_361 (aka 8u361), 11.0.18, 17.0.6, and 19.0.2 respectively). For more on each of them, including what changed and the security fixes they each contain (including their CVE scores regarding urgency of concerns), see the Oracle resources I list below. Oracle calls them "critical patch updates" (yep, CPU), but they are in fact scheduled quarterly updates, so that "critical" nomenclature may be a bit overstated. 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.

Update: After posting this, I learned of some rather surprising implications of a new feature of the new JDK installer, as 11.0.18 or 17.0.6 and later. For more, see another post I created.

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

• Finding more info on these Jan 2023 Java updates
• What about other JVM distributions besides Oracle?
• 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 with CF, etc)
• Should you apply the update? how soon?
• Beware a change in the Oct 22 JVM update regarding Java no longer trusting jars signed with SHA-1
• Beware a change in the April 2021 JVM update, if you may be skipping over it
• Wrapping up, getting more help

For now, only the Alpha has been announced, and the number of registrants allowed may be limited.

For more on that and about the prerelease (what can be gleaned/shared publicly), 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_351, (aka 8u351), 11.0.17, 17.0.5, and 19.0.1 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).

Update: After posting this, I learned of some rather surprising implications of a new feature of the new JDK installer. For more, see a new section on this below.

Oracle calls them "critical patch updates" (yep, CPU), but they are in fact 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. And if you may be skipping to this from a JVM update from before Apr 2021, I share also a bit more info as well as for users of Adobe ColdFusion (including where to find the updated Java versions from Adobe, 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 Oct 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 with CF, etc)
