22/**
23 * Unchecked variant of {@link java.util.concurrent.ExecutionException}. As with
24 * {@code ExecutionException}, the exception's {@linkplain #getCause() cause}
25 * comes from a failed task, possibly run in another thread.
26 *
27 * <p>{@code UncheckedExecutionException} is intended as an alternative to
28 * {@code ExecutionException} when the exception thrown by a task is an
29 * unchecked exception. This allows the client code to continue to distinguish
30 * between checked and unchecked exceptions, even when they come from other
31 * threads.
32 *
33 * <p>When wrapping an {@code Error} from another thread, prefer {@link
34 * ExecutionError}.
