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.

• PSU - Patch Set Update 

  • A PSU (Patch Set Update) and is a superset of the CPU (Critical Patch Update). Patch Set Updates contain all of the fixes in the corresponding CPU, as well as additional non-critical fixes.

  • See also: CPU.
• Respin
  • Sometimes there are late-arriving changes from OpenJDK that come too late to be included in the scheduled Release, or changes are discovered to be necessary after a Release has already been published. We refer to these situations and their new builds as a "respin". This is not an "official term", but it is one you may see us use for updates to scheduled Releases. 
  • Clarification with regard to BPR (Bundled Patch Release): A respin is an update to a scheduled Mainline or Update Release. A BPR is an update containing fixes or enhancements needed by one or more customers before the next scheduled Update Release. The Zulu version "build number" will be <50 for Feature Releases, Update Releases, and any "respins" of them. A Zulu version "build number" between 50 and 1000 is used for BPRs.

• SA - Subscriber Access
  • Subscriber Access builds are available only to our supported customers.
