There are many warnings when importing spring-petclinic into JBDS 10.3.0. That's expected because the purpose of this quickstart was to show by diff how few changes are required to change https://github.com/spring-projects/spring-petclinic to work with EAP. For this reason there were no changes done to fix warnings. Intention was to keep diff as minimal as possible.

Since the development (it was basically just to backport changes from original petclinc to this codebase) ceased to zero, this example really lost his original purpose.

But it was never intended to have this quickstart without warnings in JBDS, if you are still ok with this, please close the ticket.
