Steps:

• Spring PetClinic Build with FindBugs
• Determine business entities
• Determine technical entities

You can reason like

=> What if I rework my controllers (or sth else)? -> technical, crosscutting features

=> What if we shut down the JDBC feature? -> technical feature

=> What if we discontinue the support for vetenarians? -> domain feature

TODOs:

• Add FindBugs and FindBugs-Plugin to pom.xml
• Connect FindBugs results to classes
• Tag classes technical as well as business
