This article keeps referring to Java 8, Java 11, and Java 17 as LTS releases. What does that mean? Here’s a quote from the Oracle Java SE support roadmap: For product releases after Java SE 8, Oracle will designate a release, every three years, as a Long-Term-Support (LTS) release. Java SE 11 is an LTS release. For the purposes of Oracle Premier Su...
Your application contains code you and your team wrote, and it probably contains dependencies also. If something is removed from the JDK, that might break the code, the dependencies, or both. It often helps to make sure those dependencies are up to date to resolve these issues. Sometimes you might have to wait until a framework releases a new versi...
What if your application is used by customers who still use an old JDK and an upgrade at their site is out of your control? Multirelease JAR functionality, introduced in Java 9 with JEP 238, might be useful because it allows you to package code for multiple Java versions (including versions older than Java 9) inside one JAR file. As an example, cre...
Before upgrading the JDK, make sure your IDE, build tools, and dependencies are up to date. The Maven Versions Plugin and Gradle Versions Pluginshow which dependencies you have and list the latest available version. Be aware that these tools show only the new version for the artifacts you use—but sometimes the artifact names change, forks are made,...
You might see the error Unsupported class file major version 61. I’ve seen it with the JaCoCo code coverage library and various other Maven plugins. The major version 61 part of the message refers to Java 17. So in this case, it means that the version of the framework or tool you’re using doesn’t support Java 17. Therefore, you should upgrade the f...
Java 16 and Java 17 encapsulate JDK internal APIs, which impacts various frameworks such as Lombok. You might see errors such as module jdk.compiler does not export com.sun.tools.javac.processing to unnamed module, which means your application no longer has access to that part of the JDK. In general, I recommend upgrading all dependencies that use ...
I recommend that you look at the JavaUpgrades GitHub repositoryI created, which contains examples, common errors, and solutions that can help you during the upgrade process.
Upgrading your dependencies and adding dependencies for removed JDK features solves many of the Java upgrade challenges. I recommend a structured approach to upgrading step by step: First, make sure the code compiles, then run your tests, and then run the application. The migration process is a lot better if you can tell yourself, your team, and yo...

You should compare the checksum of the file you received with the value below to ensure the file you received is complete and unmodified. On Windows use certUtil -hashfile file SHA256, on Linux use sha256sum file, and on macOS use shasum -a 256 file.
For example, if there is an out-of-date JDK RPM from an 11+ release, say 11.0.17, with an incorrectly constructed single "java" group installed and 8u381 RPM with this patch is installed, it will remove an entry from the "java" group belonging to the 11.0.17 RPM and thus will switch the current system Java from 11.0.17 to 8u381.
