020/**
021 * Unchecked variant of {@link java.util.concurrent.ExecutionException}. As with {@code
022 * ExecutionException}, the exception's {@linkplain #getCause() cause} comes from a failed task,
023 * possibly run in another thread.
024 *
025 * <p>{@code UncheckedExecutionException} is intended as an alternative to {@code
026 * ExecutionException} when the exception thrown by a task is an unchecked exception. However, it
027 * may also wrap a checked exception in some cases.
028 *
029 * <p>When wrapping an {@code Error} from another thread, prefer {@link ExecutionError}. When
030 * wrapping a checked exception, prefer {@code ExecutionException}.
