/**
* {@link Error} variant of {@link java.util.concurrent.ExecutionException}. As with {@code
* ExecutionException}, the error's {@linkplain #getCause() cause} comes from a failed task,
* possibly run in another thread. That cause should itself be an {@code Error}; if not, use {@code
* ExecutionException} or {@link UncheckedExecutionException}. This allows the client code to
* continue to distinguish between exceptions and errors, even when they come from other threads.
