Announcing Java updates of Jul 15, 2025 for 8, 11, 17, 21, and 24: thoughts and resources

It's that time again: there are new Oracle JVM updates released today (Jul 15, 2025) for the current long-term support (LTS) releases of Oracle Java, 8, 11, 17, and 21, as well as the new short-term release 24. (The previous short-term release, Java 23, is no longer updated.)

TLDR: The new updates are 1.8.0_461 (aka 8u461), 11.0.28, 17.0.16, 21.0.8, and 24.0.2, respectively. More on the updates below, including links to more info on each of them including what changed, bug fixes, and the security fixes each version contains. (I also offer a quick assessment of the updates with respect to my primary audience, users of CFML engines.)

Yep, kind of crazy that there are now 5 current Oracle Java releases, for "reasons". And usually openjdk updates are released at the same time or soon after.

Oracle calls these updates "critical patch updates" (yep, "CPU"), but they are in fact scheduled quarterly updates (Jan, Apr, Jul, Oct, with specific dates listed here), so that the "critical" aspect of this nomenclature may sometimes be a bit overstated. 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.

Whether this your first time updating Java or your fiftieth, there are some things that you may or may not know.

Topics:

Finding more info on these most recent Java updates

As for what changed in the updates, see the release notes for each of 1.8.0_461, 11.0.28, 17.0.16, 21.0.8, and 24.0.2. Again, the Java 23 last updated previously in Jan 2025 is now no longer updated by Oracle, as it was in effect a "short-term" release, supplanted by 24. The others are what Oracle calls "long-term support" or LTS releases.

These Oracle release notes have sections on each of "New Features", "Known Issues", "Issues Fixed", "Other notes", and "Bug Fixes"--each as may apply to that specific update, which is why I am not listing all these changes here. See the release note for the update you are considering applying. That said, some changes may indeed be (and typically are) found in all four versions.

Quick assessment with respect to CFML engines

While the update info I share in these posts may interest ANY users of Java (indeed whether Oracle Java or OpenJDK), I'll note that the main audience for my blog are folks using the CFML engines, Adobe ColdFusion (coldfusion.com), Lucee (lucee.org) or BoxLang (boxlang.io).

And for those folks, I'll say that my assessment of this update (for all the versions) is that none of the changes (including removals or additions) seem significant to the use of Java as underlying those CFML engines (which all compile CFML into Java and run atop Java). That's not the case with all Java updates, and if you may be skipping some updates, see my discussion of that among my closing points below. And I leave you to assess the security matters discussed in the next section.

One last point on ColdFusion, related to Java updates: you must only use a Java version suited to your CF version. CF2025 runs on Java 21 (only), and CF2023 runs on Java 17 only, while CF2021 runs on Java 11 only. More on that in additional resources I link to below.

Finding more on security matters addressed in these Java updates

As for security fixes included in this update, that's covered elsewhere. You will (soon, if not now) be able to see the single document listing Java security fixes in these most recent updates and the Text Form of Risk Matrix for Oracle Java SE, for this most recent update.

As I post this, the second of the links above isn't yet available. The URLs always follow the same pattern from release to release, which is why I am offering them now. I suspect this is just some delay in Oracle getting that large "risk matrix" (covering all products) finalized today. By the time you read this, both pages may have been updated. I'm opting to proceed with this post since all the other links and info are working/accurate. When it's available, I'll comment out this paragraph.

As for that second link, pay close attention to "notes" offered there for each vulnerability, as that may temper the severity. (Note as well that while both these documents cover ALL Oracle products, I have offered in the first paragraph above links to the Java-specific sections of the pages. Focus on references to "Java SE" rather than any specific to GraalVM, which is not the focus of the discussion in this post.)

Watch also that many times the listed issues indicate that a vulnerability may be "difficult to exploit" and that many "[do] not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator)", which may reduce the concern for you about them depending on your perspective.

That said, these documents could also change between now and when you see this post, so it's your responsibility to assess that information carefully. And regardless of whether such vulnerabilities may seem to apply to you, generally folks should seek to keep their JVM updated, or at least avoid falling too far behind.

Obtaining the JVM update, from Oracle

As for obtaining downloads of Java updates, you can find all the current versions on this one page. Note that there are tabs for the installers for each supported OS (Linux, macOS, and Windows).

That said, note that while the TOP of the page offers the LATEST Java versions (Java 24 and Java 21), you will find the earlier LTS versions are instead offered LATER down the page (which is easy to miss). Here are direct links to get to them: Java 17, Java 11 and Java 8.

And while you DO need to sign in there to obtain the Java 17, 11 and 8 download files, an account is free. (The updates for Java 21 and above do NOT require a login on the Oracle site.) All this has to do with licensing of Java, which is beyond the scope of this post to discuss. (Users of Adobe ColdFusion, my primary audience, should note that Adobe licenses Oracle Java for our use of it with CF. More on that in another blog post I discuss and link to below.)

Obtaining the JVM update, from Adobe

Indeed, since the focus of my blog and work is indeed mostly focused on those using Adobe ColdFusion, I'll clarify for them that Adobe also offers the Oracle Java downloads, such that CF users need not log into the Oracle site as discussed above.

See the CF Downloads page, and its last section offering Java installers, which includes the installers or zip/archive options, for each of Windows, Linux, and MacOS. Sometimes Adobe gets these downloads posted as soon as Oracle releases them, but often it may take some days before the latest update appears, in which case consider the Oracle links in the previous section. (Note that Adobe formally supports only the use of Oracle Java, not other OpenJDK implementations.)

And while some assert that CF folks "must use those from the CF downloads page", every time I've done a binary compare of the files, they have been identical (at least for the identical build number, which may change slightly over time on the Oracle site though not the Adobe site). As this installer includes the Java license, I can't see how anyone could assert that it matters WHERE you get an identical installer. But IANAL. The choice is yours, if you want the update ASAP and Adobe doesn't offer it yet.

Other topics you may be interested to know, and where I discuss them

Some readers may find the above so far to have been "a lot to consider" already, but there is indeed far more that you could and should consider before applying a Java update. And for a few years, I would cover such additional topics within this sort of blog post, each time I announced the new JVM update. But I've decided recently to split that off into its own blog entry, and I will point to that instead in each of these such JVM update announcement posts, in order to keep this relatively "brief".

In that other post, I address such issues as :

  • Obtaining and learning still more about available JVM updates
  • What about other JVM distributions besides Oracle?
  • News for my CF audience (which CF versions support what JVM versions, how to apply the update--including when using Commandbox or Lucee, why CF users should NOT for now use Java 21 and up with CF, etc.)
  • Should you apply the update? how soon?

Then I cover a few things that you should be aware of if skipping over previous JVM updates:

Again, that other post of mine with more info is here: Several things to consider when applying JVM updates.
