jboss_init_redhat script can't stop running server

According to https://access.redhat.com/site/documentation/en-US/JBoss_Enterprise_Application_Platform/4.3/html/Installation_Guide/run_application_server_as_a_service.html

I was trying to test jboss_init_redhat.sh script to start and stop JBoss EAP as service with my local EAP 5.3 build. I found that once I started server and execute stop command, the server can not be stopped due to "No JBossas is currently running".

From the jboss_init_redhat.sh script code:

function procrunning() {
   procid=0
   JBOSSSCRIPT=$(echo $JBOSSSH | awk '{print $1}' | sed 's/\//\\\//g')
   for procid in `/sbin/pidof -x "$JBOSSSCRIPT"`; do
       ps -fp $procid | grep "${JBOSSSH% *}" > /dev/null && pid=$procid
   done
}

the sed regexp substitution changes the right path from
/home/wangchao/work/jbossas/EAP5/JBPAPP_5/build/output/jboss-5.3.0.Branch/bin/run.sh
to
\/home\/wangchao\/work\/jbossas\/EAP5\/JBPAPP_5\/build\/output\/jboss-5.3.0.Branch\/bin\/run.sh

therefore, it can't get to right procid to proceed to stop server.
