Update to spring 2

[DaGeRe]

I tried to update to Spring Boot 2.0.9.RELEASE in combination with Spring cloud Finchley.RELEASE (that should be compatible with Spring Boot 2.0.x: https://spring.io/projects/spring-cloud). This required some maven coordinate changes and some minor source code changes.

Specifying spring-data-releastrain separately, created the following problem when using mvn clean package -DskipTests && java -jar monolithic/target/monolithic-0.0.1-SNAPSHOT.jar:

To fix the spring problem, I tried to update spring-data-releasetrain.version to Ingalls-SR23 and Kay-SR14, or to remove it completely (since its already included in the regular spring boot), but this didn't change the error. The problem indicates that org.hibernate.persister.entity.SingleTableEntityPersister has a problem, but the class is in org.hibernate:hibernate-core:jar:5.2.18.Final:compile (which is part of the dependencies, as we can see using mvn dependency:tree), so I didn't see how to fix this configuring spring.

In the end, the only solution I found was updating javassist to 3.30.2-GA.
