Initial conditions :

• Maven 3.3.3
• JDK 1.8

Test procedure :

From project root & initial state (fresh from github)

1. mvn clean install (required as there are inter-modules dependencies)
2. mvn -f ./TestApiWar/pom.xml spring-boot:run

Expected :

Should boot properly. No error and http://localhost:8090/health down because the postgresql database is configured with crappy values... but the server is up and running.

Action :

1. Modify TestApiWar/pom.xml -> Uncomment the spring security and spring security oauth2 dependencies
2. mvn clean install (required as there are inter-modules dependencies)
3. mvn -f ./TestApiWar/pom.xml spring-boot:run

Expected :

Eventually boots, but with quite a lot of warnings and looping..

On this small project it does eventually boot, but on my big app is loops infinitely.
