* Azul provides three types of distribution packages for each Java version:

  • SA distributions are tested, certified, and commercially supported Azul Zulu builds of OpenJDK. Azul ensures that the software that uses the Accessible APIs of the product does not have to include specific licenses and that such use does not contaminate the code or intellectual property of such software with any license requirements.

  • NV are tested, certified, and commercially supported Azul Zulu builds of OpenJDK.

  • CA are Azul Zulu builds of OpenJDK that are free to download and use.

Known Issues

  • The Foreign Linker API (Incubator) that appeared as part of JEP-389 has a number of issues when used on Apple Silicon devices (applicable to Azul Zulu 16). The issues will be fixed in a future Azul Zulu release.
