New updates released for Java 8, 11, 17, 21, and 22 as of Apr 16 2024: resources and thoughts

It's that time again: there are new JVM updates released today (Apr 16, 2024) for the current long-term support (LTS) releases of Oracle Java, 8, 11, 17, and 21, as well as the new short-term release 22.

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.

Hi, we're new to Lucee (have previously been running on Adobe CF for some time). We've noticed that the JVM Lucee installs with is:

11.0.7 (AdoptOpenJDK) 64bit

That's obviously 4 years old and I was hoping Lucee 6 would move to a more recent one atleast. Do you have a version would you recommend running Lucee on as we're weighing up our options.

Thanks,

Chris

I'll say first that you can indeed update the jvm Lucee uses, just as you can with CF, though like CF while you can and should strive to be on the latest available UPDATE of whatever major jvm version it supports, you can't switch major jvm versions until they announce what's supported.

And for now, even Lucee 6.x does not yet support Java 17, so that would mean Java 11 for Lucee 6 and 5.

Keep an eye on this system requirements page:

https://docs.lucee.o...

as well as the Lucee forums where this question has come up often (dev.lucee.org).
