CLI Script hangs in EAP6.1.x

Issue

• Script using CLI commands hangs in EAP6.1.x but works fine in EAP6.0. Following is the script :

 #/bin/bash 

 export JBOSS_HOME="/path/jboss-eap-6.1"
 export NAME="main.log"
 export SIZE="5m"
 export BACKUP_SIZE="10"
 export DC_HOST=127.0.0.1:9999

while getopts p:h:n:l: option
do
        case "${option}"
        in  
                p) LOG_PATH=${OPTARG};;
                h) HANDLER_NAME=${OPTARG};;
                n) PACKAGE_NAME=${OPTARG};;
                l) LEVEL=$OPTARG;;
        esac
done
