Problem by configure JBoss EAP 6.x as Service on RHEL 7

I update my RHEL6 to RHEL7.7. But I must still use the Jboss EAP6.4.22 for a while. After the update of RHEL7 I have problem by starting the Jboss as a service. I've googled but till now haven't found any helpful information. Here below is my situation and what I did: After the installation of Jboss EAP 6 (RPM text installation), there is the file /etc/init.d/jbossas I enable this as service with chkconfig jbossas on. Then I create a file called /usr/lib/systemd/system/eap6-jbossas-standalone.service and it looks as follows: [Unit] Description=JBoss EAP Systemctl script After=NetworkManager.service [Service] Type=forking ExecStart=/etc/init.d/jbossas start ExecStop=/etc/init.d/jbossas stop PIDFile=/var/run/jbossas/jbossas-standalone.pid I start the jboss with systemctl start eap6-jbossas-standalone. The jboss can be started but the cursor doesn't return. I have to use the ctrl+c to get the cursor. Then I try to stop the jboss with 'systemctl stop eap6-jbossas-standalone' but the jboss can not be stopped. As I check its status with systemctl status eap6-jbossas-standalone -l I got following messages: ... # systemctl status eap6-jbossas-standalone -l ● eap6-jbossas-standalone.service - JBoss EAP Systemctl script Loaded: loaded (/usr/lib/systemd/system/eap6-jbossas-standalone.service; static; vendor preset: disabled) Active: inactive (dead) Aug 28 10:04:59 s001ap21-test-n.ad001.proactiv.grp systemd: Failed to start JBoss EAP Systemctl script.

What could be the reason?
