Quarkus 3.37 - Extension-based modularity, Hibernate ORM 7.4, Jackson reflection-free serializers, and more

Quarkus 3.37 introduces the new quarkus-jlink extension, which produces a jlink-ed modular application using jlink.

By leveraging the Java module system, jlink creates a custom runtime image that includes only the JDK modules your application actually needs, stripping out everything else. This results in significantly smaller deployment artifacts compared to shipping a full JDK, which is particularly beneficial for container-based deployments where image size matters.

When this extension is present, default JAR packaging is disabled.

This extension is experimental. Container builds, cross-architecture builds, AOT with jlink, and modular testing are not yet supported.

Have a look at the jlink guide to get started. As this is still experimental, we welcome your feedback!

Quarkus 3.37 upgrades Hibernate ORM from 7.3 to 7.4, Hibernate Reactive from 3.3 to 3.4, and Hibernate Search from 8.3 to 8.4.

Hibernate ORM 7.4 includes several behavioral and DDL changes, for instance pagination limits are now processed in SQL, and new NOT NULL constraints are added on timestamp columns. PostgreSQL minimum version is also bumped to 14. Please refer to the Hibernate ORM 7.4 migration guide for the full list of changes.

Hibernate Search 8.4 is fully backwards-compatible. See the Hibernate Search 8.4 migration guide for more details.

Also, Elasticsearch Dev Services now defaults to Elasticsearch 9.4 and OpenSearch 3.6.

Jackson’s reflection-free serializers are now enabled by default in Quarkus. This improves serialization performance by avoiding reflection-based serialization.

If you run into any issues, you can disable this optimization by setting:

and please report the problem so that we can fix it.

The REST Client introduces RestMultiResponse, which allows extraction of status codes and HTTP headers from streamed responses. Previously, getting response metadata from a streamed response required falling back to the Vert.x HTTP Client directly.

A new quarkus-rest-data-hibernate-types extension has been added. It is automatically included as a conditional dependency when both quarkus-rest-jackson and quarkus-data-hibernate are part of the application, providing better integration between the REST layer and Hibernate ORM data types.
