* 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
