After I changed "JBOSS_NAME", the EAP Linux service started with error.

Issue

• At beginning, EAP 7 run as Linux service without errors.
• After I changed JBOSS_NAME from /etc/init.d/jboss-eap-rhel.sh as below:

if [ -z "$JBOSS_NAME" ]; then
  JBOSS_NAME='jboss-eapx'
fi

• And I also changed /etc/default/jboss-eap.conf to /etc/default/jboss-eapx.conf accordingly.

• EAP Linux service will start with error:
