I was using Hudson version 1.278 without problems and now I am trying to
use the version 1.334 (and others previous) but I can't start JBoss
using the script Ant below anymore. I didn't find any error in JBoss' log.
Jboss_init_<partition>.sh is the name of the script that start/stop
JBoss.

<!-- stop jboss -->
<exec executable="${scripts.dir}/jboss_init_${partition}.sh">
<arg value="stop"/>
</exec>

<sleep seconds="30"/>

<copy todir="${jboss}/server/${partition}/deploy/"
file="target/Site.war">
</copy>

<!-- start jboss -->

<exec executable="${scripts.dir}/jboss_init_${partition}.sh">
<arg value="start"/>
</exec>
