How can I get Java 11 run-time environment working since there is no more JRE 11 for download?

by

Right now, there seem to be no free + easy Oracle-supported Java 11 JRE (only) options. Your options are:

  1. Download and use an OpenJDK Java 11 JDK from the OpenJDK site.

  2. Download and use an Oracle Java 11 JDK from the Oracle site … and be sure that you fully understand the restrictions on “commercial use” that now apply to the Oracle Java 11+ releases.

  3. Try to roll your own Windows JRE for Windows from the OpenJDK sources; see Create jre from OpenJDK Windows. (I wouldn’t recommend doing this. There are better alternatives.)

  4. Look into using the new jlink tool to create a custom image (basically a cut-down JRE) for your application. This seems to be the option that Oracle want 3rd-party application developers to use.

  5. Talk to Oracle sales about a Java support contract, and specifically ask about how to get a JRE build. (I don’t know what the answer will be. If someone does try this, and they get a positive response, please comment!)

  6. Use a 3rd-party Java JRE distribution.

    • The list of Java vendors changes over time, but as of now it includes AdoptOpenJDK, Amazon, Azul, BellSoft, IBM, jClarity, Red Hat and SAP. See also: Difference between OpenJDK and Adoptium/AdoptOpenJDK

    • Some of these vendors offer JRE distros. Check their download sites.

    • Since (nearly) all Java vendors base their products on the same standard OpenJDK codebase that is used for Oracle Java, there is no reason to be concerned about the stability of a 3rd party JRE. Some vendors offer (paid for) support.

(Or switch from Windows to Linux. I can install an OpenJDK Java 11 JRE-only package from the distro package manager on recent versions of Ubuntu, Fedora, …)

For those people who think that Oracle Java 11 and OpenJDK Java 11 are the same, please read the following from the Oracle download site:

Important changes in Oracle JDK 11 License

With JDK 11 Oracle has updated the license terms on which we offer the Oracle JDK. The new Oracle Technology Network License Agreement for Oracle Java SE is substantially different from the licenses under which previous versions of the JDK were offered. Please review the new terms carefully before downloading and using this product.

Oracle also offers this software under the GPL License on jdk.java.net/11

Notice that Oracle are saying that the licenses for Oracle Java and OpenJDK Java are different. (Not withstanding that the two are built from essentially the same source code base.) Ignore this at your peril!
