We already have an exclusion, for swagger-annotations, but in rest-tools module we have also swagger-core and swagger-models. Can be good investigate in possible problems or finally try to keep just one swagger library version in magnolia

If you add rest-tools as dependency in https://git.magnolia-cms.com/projects/PLATFORM/repos/ce/browse/magnolia-community-webapp/pom.xml then you get a compilation error:

collision: [swagger-core-2.0.9.jar, swagger-core-1.5.22.jar]
collision: [swagger-models-2.0.8.jar, swagger-models-1.5.22.jar]

We have two swagger dependency version in rest module.
