Zulu Openjdk Version 11 How To Downgrade Packages

Install The Latest OpenJDK 17, 16, 15, 13, 11 or 8 in Ubuntu, Debian or RHEL Using Zulu OpenJDK Builds.

Azul Systems provides tested, certified builds of OpenJDK, under the name of Zulu.

Zulu is free and open source software (and freely redistributable), and offers up to date OpenJDK builds of Java 17, 16, 15, 13, 11, 8, and 7.

On Linux, there are DEB and RPM packages to make it easy to install on Debian, Ubuntu, RHEL, Fedora, Oracle Linux or SLES and so on, as well as.tar.gz binaries, and Alpine Linux specific builds.

So why use the Zulu OpenJDK builds instead of Oracle Java or OpenJDK The Oracle Java license has changed for releases starting April 16, 2019.

The new license only permits certain uses, like personal and development, at no cost, requiring a commercial license for other cases.

As an example, Ubuntu 18.10 and 18.04 have OpenJDK 8u191, and Ubuntu 19.04 doesnt even have OpenJDK 8, while the latest Oracle JDK 8 and Zulu JDK 8 is version 8u212.

Also, OpenJDK 12 is only available on Ubuntu 19.04.

Heres the OpenJDK situation in Ubuntu.

Whats more, an analysis is ran to ensure that every single compiled file has the correct GPLv2 with CPE license header, guaranteeing that you dont encounter licensing issues when using Zulu OpenJDK builds.

Zulu OpenJDK 17, 16, 15, 13, 11, 8 or 7 builds for Windows, macOS and Linux can be downloaded from this page.

Zulu OpenJDK is also available in repositories (for 64bit only) provided by Azul Systems, for Debian, Ubuntu and other Debian or Ubuntu based Linux distributions like Linux Mint, elementary OS and so on, as well as RHEL, Oracle Linux or SLES.

The repositories retain older package versions, so for example, you can downgrade the package to the version that was available before the last update, in case something goes wrong with the latest release.

Zulu Openjdk Version 11 How To Downgrade Packages

See how to downgrade packages (in general) on Debian or Ubuntu.

Both the DEB RPM packages and the repositories packages update the Java alternatives in order to make Zulu OpenJDK default.

If you are using the oracle-java15-installer (or older) on DebianUbuntu, you must remove the oracle-java15-installer-set-default package to get Zulu OpenJDK to be the default system Java.

The Zulu OpenJDK packages do not include desktop integration, so you wont find any OpenJDK desktop files in your application menu, or have the option of opening some JAR file from the file manager with Zulu OpenJDK.

Import the Zulu repository key and add the Zulu repository as follows: Ubuntu, Linux Mint, and other Ubuntu-based Linux distributions that support add-apt-repository.

Extra Zulu OpenJDK links you may find useful: There are also open source builds of Zulu with OpenJFX (11 and 8), but those only come in archives, and not as DEB or RPM packages.
