Historique du projet

Open Liberty descends from IBM Liberty, created in 2012 for a smaller, modular application-server model and released as open source in 2017. The project became IBM's public development base for a runtime that implements Jakarta EE and MicroProfile while also underpinning WebSphere Liberty.

Jakarta EE 9 and 9.1 were historically significant because they changed the package namespace from `javax` to `jakarta`. Open Liberty tracked that shift in its features: the Jakarta EE 9.1 platform feature combines the Liberty features for the full platform and uses `<feature>jakartaee-9.1</feature>` in server configuration.

Historique d'adoption

Open Liberty was part of the Jakarta EE 9.1 ratification story: the project stated that its beta was compatible with both the Jakarta EE 9.1 Web Profile and Platform specifications using Java SE 8 and Java SE 11. That positioned Liberty as an early implementation for teams testing the namespace migration before larger fleet moves.

The package's adoption role is therefore migration-oriented. It gives developers a packaged runtime for validating applications, build pipelines, and server.xml feature configuration against the Jakarta EE 9 generation rather than the Java EE 8/Jakarta EE 8 compatibility line.

Modes d'utilisation

A developer selecting this package is usually dealing with applications or libraries that have moved to the `jakarta.*` APIs. In Open Liberty, enabling the platform pulls in the Jakarta EE Web Profile plus full-platform components such as connectors, messaging, mail, XML binding, XML web services, and application-client support.

The broader Open Liberty workflow supports Maven, Gradle, Docker, and IDE tooling, but the Homebrew formula provides a simple package-manager route for local testing and operations scripts that expect a named runtime package.

Pourquoi les passionnés de paquets s'y intéressent

openliberty-jakartaee9 is a clean example of a package name carrying standards-version semantics. The distinction from openliberty-jakartaee8 is not cosmetic: Jakarta EE 9 is the namespace migration line, so package catalogs need to treat it as a different compatibility target.

It also shows why runtime packages for Java servers can age differently from the upstream project. A formula may be preserved to serve a standards line even while Open Liberty itself keeps releasing newer Jakarta EE platform levels.
