Раньше у нас была среда с Oracle 12 C совместимым ojdbc8.jar в tomcat / lib. Который работал нормально.
Мы обновляем Oracle до 19 C и, соответственно, драйверы JDB C. Мы загрузили новые драйверы с: https://www.oracle.com/database/technologies/appdev/jdbc-ucp-19c-downloads.html
Имея только ojdbc8.jar в tomcat / lib, tomcat записывает в журнал следующее предупреждение.

Зная, что Oracle кошелек не используется, насколько важно было бы игнорировать это предупреждение?
Есть ли способ избежать такого предупреждения при запуске сервера? ИЛИ Добавление oraclepki.jar (и нескольких других впоследствии) - единственный вариант?
