* Maven profiles to support jdk 11 builds. #948 Added maven profiles activated by jdk 11, wich will not break java 8 support. Bumped lombok and datanucleus enhancer as the old versions dont work with 11. * Fixed PMD issue when building naked-objects * Fixed the eip modules with xml dependencies. Previous dependency relaxing commit causes xml libs to go missing from some modules that actually needed them

Intent
Service Layer is an abstraction over domain logic. Typically applications require multiple kinds of interfaces to the data they store and logic they implement: data loaders, user interfaces, integration gateways, and others. Despite their different purposes, these interfaces often need common interactions with the application to access and manipulate its data and invoke its business logic. The Service Layer fulfills this role.
Applicability
Use the Service Layer pattern when
- you want to encapsulate domain logic under API
- you need to implement multiple interfaces with common logic and data
