New updates released for Java 8, 11, 17, and 18 as of Jul 19 2022

Here's a heads-up that some will want to hear about: there are new JVM updates released today (Jul 19, 2022) for the current long-term support (LTS) releases of Oracle Java, 8, 11, and 17, as well as the new interim update 18. (Note that prior to Java 9, releases of Java were known technically as 1.x, so 8 is referred to in resources below as 1.8.)

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

My presentation will open CF DevWeek this week: CF, more modern than most realize

Just thought I'd post a reminder for folks that I am giving the opening session for the 2022 CF Dev Week, running July 18-22. Registration is free, of course.

My session will be at 9a 930a Eastern on Monday July 18:

Java 10 added a var keyword that is quite different from that in CFML

Did you know that Java 10 (and above) has added use of a "var" keyword in variable declaration? Note that it's quite different from CFML's var keyword.

This is NOT something that CF developers NEED to know, and it WILL NOT affect anyone's CFML code.

I just thought I'd share news of it as I happened to learn of it today (though Java 10 came out nearly 5 years ago). More than anything, I thought it worth mentioning for the sake of either CF folks or Java folks who may come to work with CFML, to help each group understand how that Java var keyword is so very different from the one used in ColdFusion, for better or worse.

What's new FusionReactor 8.8.0, released Jul 12, 2023

Good news for FusionReactor users: a new version, 8.8.0, has just been released. You can see a list of several bullet points about it in the release notes. Most of the improvements will benefit those using the traditional on-premise version of FR, while the couple that refer to FR Cloud are rather minor.

TLDR: If it's enough for you to know that FR is now updated and those bullets may suffice, you now have what you need to know. :-) In this post, I want to expand on the very brief bullets in those release notes, to give more context and screenshots.

FWIW, I have no inside info or advanced knowledge of the release: this comes from my own assessment of things as I just applied the update this morning. As such, I could be wrong on some points, or may need to come back to clarify something. But in the meantime, I hope this overview may help folks, as sometimes the single bullets in the release notes can leave you wondering. :-)
