You actually have a clean start, I thought the same thing when I first started setting up the SOA platform and thought it was getting stuck on:
2012-08-17 22:07:52,363 INFO [org.hibernate.util.NamingHelper] (Thread-25) JNDI InitialContext properties:{}
If you actually look in the logs, you will see:
2012-08-17 21:36:57,994 INFO [org.jboss.bootstrap.microcontainer.ServerImpl] (main) JBoss (Microcontainer) [5.2.0.GA_SOA (build: SVNTag=5.2.0.GA_SOA date=201111090730)] Started in 1m:23s:702ms
Which means the AS started up, however if you are running the machine on a remote box and are remotly accessing it from your desktop then you need to do the following when you start it up:
/run.sh -b 0.0.0.0
This is to get the AS to bind to all IP's your device has, alternatively you can do -b yourIpAddress instead. Otherwise when you hit http://yourIpAddress:8080 you get nothing.
