- Неподдерживаемая версия major.minor 52.0 означает, что у вас есть проблема совместимости версии JDK с вашим сервером Web/Application.
- Измените его на более высокий JDK, предпочтительно JDK 1.8 (рекомендуется), и повторная компиляция кода решит вашу проблему.
- В этом сценарии настоятельно рекомендуется использовать tomcat 8.X + JDK 1.8 для решения вашей проблемы.
