Download quickstart spring-boot-camel-config with spring-boot 2 from [1]
Follow README.md and get error.

• Error during jUnit Test:

  ***************************
  APPLICATION FAILED TO START
  ***************************

  Description:

  The bean 'servletRegistrationBean', defined in class path resource [org/apache/camel/component/servlet/springboot/ServletMappingAutoConfiguration.class], could not be registered. A bean with that name has already been defined in io.fabric8.quickstarts.camel.Application and overriding is disabled.

  Action:

  Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

Caused by code [2] - renaming removes this error.

• Error on Openshift
  Even with previous error fixed and successful jUnit test, quickstart fails with following error. Seems to be some kind of problem during db initialization.
