[jboss-as7-dev] path for common libraries

Dear AS devs, I was looking at the structure of the Beta3 release. Both standalone and domain contain a "lib/ext" path. Is it intended as replacement for common/lib of earlier JBoss AS releases ? Later on I'd like to extract Classloading information for classes loaded in this path and see how it compares with the libraries loaded in the "modules" repository. Will post a follow-up. Thanks, Francesco
