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, just released?

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. :-)

Understanding the "cost" of cflock, part 1

In a post today on his blog, Ben Nadel did an experiment "Looking At The Performance Overhead Of A Read-Only Lock". (He happened to do it in Lucee, but the concept applies equally to CF.)

And I wanted to offer some additional thoughts--first planning to offer them as a comment--because there's a lot behind the question and his observations. But as it got longer, I realized it was too long for a comment. Also, I didn't want people to think (in reading a comment on Ben's blog) that I was challenging Ben or questioning his understanding of the matter! Not at all. :-) Instead, I was just wanting to add more context, to help other readers, and based on my years of observing the community.

What I offer here is pretty much exactly what I wrote, but I have added headings, to help readers here:

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

New JVM updates have been released today (Apr 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, to 8 is referred to in resources below as 1.8.)

The new updates are 1.8.0_331, (aka 8u331), 11.0.15, 17.0.3, and 18.0.1 respectively). And as is generally the case with these Java updates, most of them have the same changes and fixes.

For more on them, including changes as well as the security and bug fixes they each contain, see the Oracle resources I list below, as well as some additional info I offer for if you may be skipping to this from a JVM update from before Apr 2021. I also offer info for Adobe ColdFusion users on where to find the updated Java versions, what JVM versions Adobe CF supports, and more.

Exciting news coming in FusionReactor webinar this Thursday

The FusionReactor folks will offer a webinar this Thurs, Mar 24, at noon US Eastern, "Introducing Distributed tracing and on-prem observability".

I highly recommend that FusionReactor users (and others) register. (Even if you can't attend, you will get access to the recording.) It's about some totally new capabilities:

  • Note that it's about changes coming in both the FR Cloud and in the traditional "on-prem" FR UI. As such, the new capabilities should be very compelling even for those FR users who have not yet bothered to (or for some reason cannot ) use FR Cloud
  • Also, it's about more than what's been made available yet to those beta testing the new "logging" feature in FR Cloud
  • Finally, for those who DO use FR Cloud, there may be discussion of upcoming changes regarding the FR Cloud UI itself

FusionReactor 8.7.7 released, enhances the recent DB and API Time feature

I had blogged in early November about how FusionReactor 8.7.4 had added at that time a new feature where it lists on request summary pages the DB and API Time of each request, so you could readily tell how much of a request's duration might have been caused by time spent waiting for either of those kinds of resources.

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.

New updates released for Java 8, 11, and 17, as of Jan 2022

New JVM updates have been released last week (Jan 18, 2022) for the current long-term support (LTS) releases of Oracle Java, 8, 11, and 17. (Note that prior to Java 9, releases of Java were known technically as 1.x, to 8 is referred to in resources below as 1.8.) I'd shared the news in a tweet last week, but was delayed in getting this post out.

The new updates are 1.8.0_321, (aka 8u321), 11.0.14, and 17.0.2, respectively).

For more on them, including information on the security fixes and bug fixes they each contain, see the Oracle resources I list below, as well as some additional info I offer for 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.

About the log4jshell pandemic, and what CF folks can do about it

Updated later Dec 14, 17, 21, 28, then Jan 11. See more below.

You can find lots of info in the CF and IT worlds about the log4jshell (or log4shell) "pandemic", since the news broke late Dec 9. If you have not found those yet, first here's a post I did on the Adobe CF portal yesterday with my thoughts (and a "mask" to consider, especially while we await a formal update, "the shot", from Adobe):

My lengthier post at the CF Portal: Dealing with the recent log4j vulnerability, before Adobe releases an update

I have more that I offered originally in this post here, on my carehart.org blog, but first I want to track recent updates and news since I first posted these two blog entries on the morning of Dec 14:
