sorry, I was in a hurry when I reported.
There's no error message - it simply times out.

I'd set log level to DEBUG but I haven't found how: http://cargo.codehaus.org/Maven2+Plugin+Reference+Guide
IIRC, JBoss AS plugin starts by calling run.sh from Ant, and then checks if it's started by HTTP requests to some jsp or such.
The JBoss AS process is not started at all, so the problem is most probably in the code calling run.sh.
I am not aware of any changes in EAP which would break the run.sh API.
