21 * Unchecked variant of {@link java.util.concurrent.ExecutionException}. As with {@code
22 * ExecutionException}, the exception's {@linkplain #getCause() cause} comes from a failed task,
23 * possibly run in another thread.
24 *
25 * <p>{@code UncheckedExecutionException} is intended as an alternative to {@code
26 * ExecutionException} when the exception thrown by a task is an unchecked exception. However, it
27 * may also wrap a checked exception in some cases.
28 *
29 * <p>When wrapping an {@code Error} from another thread, prefer {@link ExecutionError}. When
30 * wrapping a checked exception, prefer {@code ExecutionException}.
