I just compiled the current snapshot of JBoss 7.2.alpha1. Next I tried to configure a JBossAS community server with JBoss Tools 4.0.0 using the server adapter for JBossAS 7.1.
However, the configuration fails because the subdirectory "modules" has a new structure. Especially, "modules/org/jboss/as/server/main" now is "modules/system/layers/base/org/jboss/as/server/main".
