After upgrading to the (now) latest EAP, build #7584, and upon restarting IDEA, it detected a new Spring facet.
What does this mean? What is it telling me? Why did it only appear now?
If I seem to be ignorant of my own project, it's because it includes a Grails application which uses Spring, Hibernate and other open-source packages "under the hood." It builds a J2EE servlet, which I've configured as a Content Root in a module of this project. The newly detected Spring facet lies within the Grails Web App directory.
