Minimal example showing brevo's https://github.com/sendinblue/APIv3-java-library failing with tomcat 7

The following fails:

mvn clean tomcat7:run-war

Whilst running unpacked succeeds:

mvn clean tomcat7:run

Temporary solution

Updating the transitive dependency in the API library is a temporary solution.
