Я создал новый проект с Spring Boot и camunda-bpm-spring-boot-starter.Как запустить Camunda с помощью HSQLDB?
Обычно я использую встроенный HSQLDB в тестах интеграции. Но когда тесты выполнены с HSQLDB и Camunda контекст весна не заводится:

С помощью свойства camunda.bpm.database.type = hsqldb есть другое исключение:

Так как я могу использовать Camunda с в памяти HSQLDB?
