022 * An exception class used for reporting error conditions related to accessing data of background tasks.

026 * it wraps an exception that occurred during the execution of a task. However, in contrast to
027 * {@link ExecutionException}, it wraps only checked exceptions. Runtime exceptions are thrown directly.
