Azul Terms Glossary

Here are definitions of commonly used terms and acronyms used by Azul. 

This glossary is a work in progress. Please don't hesitate to let us know of terms you come across in our software or documentation that you'd like us to define here.

Most of these terms are used in the context of Azul Zulu Builds of OpenJDK. Where they are used for Azul Zulu Prime JDK or other Azul products the same definitions apply unless otherwise specified.

• Respin
  • Sometimes there are late-arriving changes from OpenJDK that come too late to be included in the scheduled Update Release, or changes are discovered to be necessary after an Update has already been released. We refer to these situations and their new builds as a "respin". A respin is a type of Bundled Patch Release (BPR). 
• SA - Subscriber Access
