systemd unit file not working on RHEL8

It seems the supplied systemd unit file in jfrog-artifactory-pro-6.12.2-61202900.noarch doesn't work with RHEL8:

host:~# systemctl start artifactory
Job for artifactory.service failed because the service did not take the steps required by its unit configuration.
See "systemctl status artifactory.service" and "journalctl -xe" for details.

host:~# systemctl status artifactory
● artifactory.service - Setup Systemd script for Artifactory in Tomcat Servlet Engine
Loaded: loaded (/usr/lib/systemd/system/artifactory.service; enabled; vendor preset: disabled)
Active: activating (auto-restart) (Result: protocol) since Fri 2019-09-27 09:18:22 CDT; 3s ago
Process: 21863 ExecStart=/opt/jfrog/artifactory/bin/artifactoryManage.sh start (code=exited, status=0/SUCCESS)

 The process clearly seems to be running, though (but now is not being properly managed by systemd for stop/restart, etc.):

artifactory:~# ps auxw | grep artifactory

I've attempted to fix the unit file, by starting Tomcat directly as the "artifactory" user, setting the environment variables directly, changing from "Type=forking" to "Type=simple", etc.  I can't get it to start properly, which makes it impossible to manage correctly with Puppet (systemd really needs to properly manage the process with correct running / not running status).
