Zulu Commercial Compatibility Kit Downloads

Zulu® and Zulu Enterprise Commercial Compatibility Kit

The Zulu Commercial Compatibility Kit (ZCCK) is designed to ensure compatibility of Zulu (Azul’s 100% open source, certified builds of OpenJDK) and Oracle’s proprietary Java SE 6-8. This Kit contains additional functionality that is not included in the OpenJDK project source, but which will help ensure compatibility in applications that take advantage of specific additional features that Oracle bundles into its commercial Java products.

The Zulu Commercial Compatibility Kit is free to download and use and can be added easily to Zulu as part of your normal software update process. Please review the ZCCK Terms of Use. By downloading the ZCCK you are agreeing to these terms of use and acknowledging that you will comply with these Terms of Use when applying the ZCCK to your Zulu deployments. All versions of the Zulu Commercial Compatibility Kit includes the Lucida font family from Monotype™.

To make use of the ZCCK for OpenJDK versions 6-8, first, download Zulu and deploy it on target OS environments as you normally would. Then choose the ZCCK version below that matches both your operating system and installer (this is very important). You may use the ZCCK for any free Zulu or subscription-based Zulu Enterprise deployments. An online version of the Zulu documentation is available here (for all platforms) with Zulu Commercial Compatibility Kit as a topic.

Important note:

After Java SE 8, Oracle changed how the JDK supports fonts, leaving font management up to the target operating system instead of the JDK. 

Note that Lucida fonts are licensed by Azul from Monotype for internal use only. If your product plans require that these fonts be made available to your end customers, please contact your Azul representative immediately.
