Ошибка компиляции аннотаций гибернации

У меня возникает странная проблема, когда я пытаюсь скомпилировать файл DTO, который имеет аннотации спящего режима для сопоставления с базой данных. при сбое со странным журналом сообщений ниже. в чем может быть причина этой проблемы? Я полагаю, что ошибка происходит из файла CashDTO. что я делаю не так в файле CashDTO.java?[12126ptingError log:
