+
+Let's assume you have a `CustomTaskDecorator` that implements Springs `TaskDecorator` API.
+You want to invoke an `ResultT customOperation()` via the `ResilienceDecorator` API.
+This internally requires handling of additional threads and their contexts.
+You can use the `AtomicReference` container to store information between threads.
+
+```java
+@Autowired
+CustomTaskDecorator decorator;
+
+// ...
+
+AtomicReference<ResultT> result = new AtomicReference<>();
+Runnable decorated = decorator.decorate(() -> result.set(customOperation()));
+
+ResultT resilientResult = ResilienceDecorator.executeSupplier(() -> {
+  decorated.run();
+  return result.get();
+}, customResilienceConfiguration);
