 # Quarkus - Hibernate and Hibernate Validator (lazy fetch strategy)
 This scenario uses in-memory Java database H2.  
-Test class annotated with `@QuarkusTestResource(H2DatabaseTestResource.class)` starts an in-memory H2 database
+Test class annotated with `@QuarkusTestResource(H2DatabaseTestResource.class)` starts an in-memory H2 database
+
+Module that covers integration with some Hibernate features like:
+- Reproducer for [14201](https://github.com/quarkusio/quarkus/issues/14201) and [14881](https://github.com/quarkusio/quarkus/issues/14881): possible data loss bug in hibernate. This is covered under the Java package `io.quarkus.qe.hibernate.items`.
