`NoSuchElementException` from `ServiceLoader` in Async Context

This report details a critical runtime exception encountered for derivatives trading (USDS Futures) within a Play Framework 3 / Pekko environment.

When initializing the WebSocket client within a `CompletableFuture` (e.g., on Play's default `ForkJoinPool`), the `ServiceLoader` mechanism fails to find Jetty WebSocket extension implementations.

- **Error:** `java.util.NoSuchElementException` originating from `java.util.ServiceLoader` and traced up through `org.eclipse.jetty.websocket.api.ExtensionConfig.getParser`.
- **Cause:** The `ServiceLoader` relies on the `Thread.currentThread().getContextClassLoader()`. When the initialization code runs on a worker thread from a thread pool (like `ForkJoinPool`), this context classloader may not have visibility of the full application dependency classpath where the Jetty service implementations reside.
- **Trigger:** Instantiating `new DerivativesTradingUsdsFuturesWebSocketStreams(wsConnectionPool)` inside a `CompletableFuture.supplyAsync()` block.

Inizia tracciando DerivativesTradingUsdsFuturesWebSocketStreams quando viene creato all’interno di CompletableFuture.supplyAsync(), quindi esamina ServiceLoader e org.eclipse.jetty.websocket.api.ExtensionConfig.getParser nel contesto Play/Pekko segnalato. Riproduci il fallimento su un worker di ForkJoinPool e conferma in che modo differisce il classloader del contesto; il report non definisce né la correzione prevista né un test di completamento.
