/**
 * <h2>GetPropertiesResponse</h2>
 *
 * <p>Concrete JAXB response wrapper class responsible for unmarshaling<br>
 * the downstream XML payload returned by the {@code getProperties}<br>
 * SOAP operation. This entity serves as the formal structural envelope<br>
 * containing a collection of targeted configuration properties matching<br>
 * the key array sent in the request.</p>
 *
 * <p><b>Architectural Context &amp; Serialization Mechanics:</b><br>
 * Modernized and stabilized for compliance with <b>Java 21</b> and<br>
 * <b>Spring 6.1</b> infrastructures. Fields are bound directly using an<br>
 * explicit strategy managed via {@link XmlAccessorType} set to<br>
 * {@link XmlAccessType#FIELD}. The underlying data array is mapped to<br>
 * the wire under the specific schema element alias {@code "return"}<br>
 * via the {@link XmlElement} metadata annotation, ensuring strict<br>
 * sequencing via the class-level {@code propOrder} parameter.</p>
 *
 * <p><b>Memory Management &amp; Non-Blocking Workloads:</b><br>
 * The internal backing collection {@code _return} is marked as required<br>
 * and nillable. To maximize runtime performance within highly parallel<br>
 * pipelines running on Java 21 Virtual Threads, the collection accessor<br>
 * uses a lazy-initialization pattern. This guarantees that a non-null<br>
 * {@link ArrayList} instance is safely provided on invocation. Consumers<br>
 * should leverage modern high-performance iteration or array blitting<br>
 * techniques when copying data to prevent memory churn or context<br>
 * blocking states within shared worker scopes.</p>
 *
 * <p>The class exposes the following target retrieval vector:<br>
 * <ul>
 * <li>{@code getReturn()}: Explicitly returns the underlying {@link List}<br>
 * of compiled {@link Property} entities, instantiating an empty backing<br>
 * container on the fly if the incoming wire block was null.</li>
 * </ul>
 *
 * @since CPLS Migration 2.0 (Java 21 / Spring 6.1 Baseline)
 * @see ConfigurationRetrievalServicePortType
 * @see Property
 * @see XmlRootElement
