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

Here's a heads-up that some will want to hear about: there are new JVM updates released today (Oct 18, 2022) for the current long-term support (LTS) releases of Oracle Java, 8, 11, and 17, as well as the new interim update 19. (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_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).

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)
  • 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

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.

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).

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.

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.)

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.

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.

New updates released for Java 8 and 11 (and 17), Oct 2021

New JVM updates have been released yesterday (Oct 19, 2021) 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.) While the news has been announced by Oracle and shared in the IT press, I know that some of my readers don't necessarily follow those sources closely.

The new updates are 1.8.0_311, (aka 8u311), 11.0.13, and 17.0.1, 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.

Lots more to the current CF2021, 2018 prerelease than folks may realize

Have you checked out the many things coming in the updates for CF2021 and 2018 in prerelease the past few weeks? Anyone is welcome to join the prerelease, logging in with an Adobe account. It's a lot more substantial than I think most realize.

New updates released for Java 8 and 11, April 20 2021

For those using the Long-term Support (LTS) versions of Oracle Java, 8 and 11, please note `there were new updates released last week (Apr 20), specifically Java 11.0.11 and 8.0_291. For some, that's all they need to hear. They will take that ball and run with it.

For most, you should read on, especially about an important change regarding TLS support (and calling out to servers not yet running TLS 1.2 or above). I cover that and other important topics:

  • What's in the JVM update, do you need to update to it?
  • A key change in this Java update: calls out to TLS 1.1 or 1.0 no longer allowed, by default
  • Re-enabling support for calling out to old TLS versions
  • Groundhog day: you'll need do make this java.security file change on any later JVM updates
  • Should you update to the new JVM version?
  • The importance of testing such updates/changes
  • More questions you may surely have, and finding answers to them
  • Obtaining the updated Java installers

Confirming ColdFusion's Java version via CFML code

Have you ever wished you could confirm with 100% certainty what Java version is in use by the CF instance you are running? Or where the JVM's location is (in case you are told to modify files related to it)?

Some good news is that ColdFusion offers simple ways/variables that can show you each of these, via CFML code. In this post, I share that. I share first a simple single variable which works in CF2018 and above, then I offer a variation for those on CF2016 and earlier, as well as variations for Lucee.

New updates released for Java 8 and 11, Oct 2020

For those using the Long-term support (LTS) versions of Oracle Java, 8 and 11, please note that there were new updates released last week (Oct 20), specifically Java 11.0.9 and 8.0_271. For more on each, see the:

For some, that's all they need to hear.

And I could (and probably should) leave it at that. But there are other questions which folks will have, including more on getting those binaries/installers (from Oracle or Adobe), on the difference between those LTS versions and "more recent" Java versions, as well as non-Oracle JVMs, and on licensing matters and more. For those, read on. Perhaps I will split this other stuff out into its own post at some point, so I can just point to it from news of these Java updates.
