Oracle Java has a new license starting APril 16, 2019. The new license is only free (no cost) for personal and development use, while other uses require a paid, commercial license.
And that's not all. Only Oracle Java 12 can be downloaded without an Oracle account right now. Older Oracle Java versions, like 8 and even the long term supported Java 11, need an account to be abvle to access the download links.
Sol what alternatives are there, that offer open source, freely distributable and up to date OpenJDK builds? Well, there are a few OpenJDK builds out there, and below you'll find 2 you can use.
AdoptOpenJDK offers prebuilt OpenJDK binaries for free, with all binaries and scripts as open source software.
Right now they have OpenJDK 8, OpenJDK 11 and OpenJDK 12 for download, as well as HotSpot and OpenJ9 JVMs. As for platforms, AdoptOpenJDK has binaries for Linux (x64, s390, arm32, aarch64, ppc64le), Windows (x32 and x64), and macOS (x64).
Nightly builds are also available.
Azul Systems is a company that provides Zulu OpenJDK, which are tested, certified, and free OpenJDK builds.
Zulu OpenJDK is open source software, and the builds are freely distributable. According to someone working on Zulu, an "analysis is ran to ensure that every single compiled file has the correct GPLv2 with CPE license header, guaranteeing that you don't encounter licensing issues when using Zulu OpenJDK builds."
Currently they provide OpenJDK builds of Java 12, 11, 8 and 7, for Windows, Linux and macOS. There's also Zulu Embedded, available for Arm v8/v7/v6 soft and hard float ABI.
On Linux, Zulu OpenJDK has not only DEB and RPM packages for download, but also offers DEB and RPM repositories so you can easily update the Zulu OpenJDK packages to the latest version.
These are the two OpenJDK builds that I could find which come with free, open source licenses, and are freely redistributable. There's also Red Hat OpenJDK, but I didn't look into the license, but what I noticed is that they only offer public OpenJDK builds for Windows (and the sources). Amazon has its own Amazon Corretto, a no-cost, multiplatform and production-ready distribution of OpenJDK for Linux, Windows and macOS, but it's not distributed with an open source license.
