    020 * <p>
    021 * An exception class used for reporting error conditions related to accessing
    022 * data of background tasks.
    023 * </p>
    024 * <p>
    025 * The purpose of this exception class is analogous to the default JDK exception
    026 * class {@link java.util.concurrent.ExecutionException}, i.e. it wraps an
    027 * exception that occurred during the execution of a task. However, in contrast
    028 * to {@code ExecutionException}, it wraps only checked exceptions. Runtime
    029 * exceptions are thrown directly.
