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.

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

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

• release notes for java 11.0.9
• release notes for java 8.0_271

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.

Perhaps you're getting errors referring to "metaspace" or "OutOfMemoryError: Metaspace", whether in your web sites, error logs, or even the CF Admin, and you wonder "what to do". Or you may be getting odd occurrences of blank pages, and if you look in your coldfusion-error.log you are finding such metaspace errors.

TLDR; In all these cases, the solution is simple (and may seem contrarian to some ears): REMOVE the maxmetaspace element from your JVM arguments. Indeed, I would go so far as to say everyone should simply remove it, even BEFORE you may get errors.

In the post that follows, I will explain how to remove it, including how you need to be VERY careful when doing that. You may also wonder why I recommend removing it, versus raising it. I cover that, as well as a bug report I filed with Adobe related this tis (which was fixed as of CF2021), below.

I also created an abbreviated version of this post, on the Adobe CF portal, if that may interest some readers.

Bottom line: these limitations DO apply to ANY PRODUCTION use, not just "commercial" use, definitely regarding Java 11, and seemingly clearly regarding Java 8.

For more clarification, read on.
