Problem

[brunogenovese]

What I find most puzzling is that I most often get this error with Spring Boot applications that do not use JDBC, JDBC starter, or any other dependency that should be expecting a JDBC configuration.

I suspect that the unexpected dependency might come from one of the following starters but I have not discovered which yet:

• spring-boot-starter-parent
• spring-boot-starter
• spring-boot-starter-log4j2
• spring-boot-starter-web
• spring-boot-starter-tomcat
• spring-boot-starter-test
