To install Oracle AIA 11.1.1.5.0 with SOA Suite 11.1.1.5.0 you need a JDeveloper installation.
Apparently it's a very bad idea to install JDeveloper in the same MIDDLEWARE_HOME as the Middleware Products as it causes conflicts with Java Faces
So if your AIA installation fails because it can't restart the servers during the installation take a look in your server log files. If you see errors where it complains that it can't find javax/faces/application/ProjectStage make sure your JDeveloper installation isn't in the same MIDDLEWARE_HOME.
