+## Interaction with other open source projects
+
+One of the best parts about working on the Spring Petclinic application is that we have the opportunity to work in direct contact with many other Open Source projects. We found some bugs/suggested improvements on various topics such as Spring, Spring Data, Bean Validation and even Eclipse! In many cases, they've been fixed/implemented in just a few days.
+Here is a list of them:
