This feature enables support for the Jakarta RESTful Web Services 3.1 Client API.

Jakarta RESTful Web Services, formerly known as JAX-RS, is a Jakarta EE platform API. In Open Liberty 21.0.0.12 and later, you can use Jakarta RESTful Web Services 3.0 client functions by enabling the RESTful Web Services Client 3.0 feature. The JAX-RS 2.0 and 2.1 client implementations are available through the Java RESTful Services Client feature (jaxrsClient-2.0 and jaxrsClient-2.1). The change in feature name and version reflects the change in API package name prefixes from javax.* to jakarta.*, which is common to all Jakarta EE 9.1 features. For more information, see Differences between Jakarta RESTful Web Services 3.0 and Java Restful Services (JAX-RS).
