New features

This section describes the new features of the {ProductName} ({ProductShortName}) {ProductVersion}.

Rules for migrating from Java EE8 to Jakarta EE9

{ProductShortName} rules replace Java EE8 artifact dependencies and package import statements and rename XML schema namespaces, prefixed properties, and bootstrapping files for Jakarta EE9.

Most rules contain quick fixes to automate source code changes when using an {ProductShortName} IDE plugin or extension for Eclipse, Eclipse Che, IntelliJ IDEA, Microsoft Visual Studio Code, or Red Hat CodeReady Studio.

To execute the rules, use the target jakarta-ee.

OpenRewrite recipe support

OpenRewrite automates large-scale, distributed source code refactoring. You can execute OpenRewrite recipes by using the {ProductShortName} CLI.

The first OpenRewrite recipe, which is shipped with {ProductShortName} 5.2.1, renames imported javax packages to their jakarta equivalents.

Important

OpenRewrite recipe support is provided as Technology Preview only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs), might not be functionally complete, and Red Hat does not recommend to use them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

See Technology Preview features support scope on the Red Hat Customer Portal for information about the support scope for Technology Preview features.
