Im afraid you are not going to get much support on AS 6 anymore, but you could try to run the jstack tool and see where and why it's stuck.
why I don´t will get support? AE6 is deprecated now?
My doubt is if my spring+hibernate simple .war works or not in Jboss. I read in some foruns that I must change my code because Jboss ships withe some custom spring jars.
