Folks using ColdFusion will want to be aware that last week (Jan 19, 2021) Oracle has released updates to Java 11 and Java 8, the current “Long-Term Support” versions of the Java JVM/JDK, which are supported by the various current and recent versions of CF. The downloads are available on the Adobe page where Adobe offers JVM updates. More about how to proceed to implement the update, in a moment.
As for which version of Java you should be using, for your version of CF, see a helpful table I created.
As for configuring CF to use a new Java update, there have been many resources from various folks, including from Adobe and others. See this resource I offer with more on the topic.
Finally, do beware that things can go amiss, if you are not careful. I address those possible problems (and solutions) in this post, CF911: ‘Help! I’ve updated the JVM which ColdFusion uses, and now it won’t start!’. Both those resources offer a link to get direct help in solving such problems, if needed.
Updating the JVM that CF uses (the latest version that it supports) is an important responsibility. It may be a bit like flossing if you may not enjoy that, but at least you don’t have to do it as often. 🙂
