CentOS 7 custom service failure (Interactive authentication required)

I am trying to setup an OFBiz fork called Scipio as a service on CentOS 7.

The service wrapper script changes the user to a dedicated one for the program. All of the program's files are owned and in the group under that dedicated user name.

If I grant execute permissions on the script, have it sitting in a sub directory of the program, and log in as that dedicated user, and execute it directly like a standard bash script it functions perfectly. BUT, if I copy it to /etc/rc.d/init.d/scipio and attempt to execute it as another user (my normal account) using sudo, (executing "normally" or as service), it fails.

It looks like the error is something to the effect of:

failed to start service interactive authentication required

Here are the permissions (ls -l):

-rwxr-xr-x. 1 root root 4165 Jul  8 16:00 /etc/rc.d/init.d/scipio

Here's how I like to launch it (as a sudoer):

sudo service scipio restart

Here's the script itself:

It seems like this is a CentOS 7 specific issue. I believe the services model changed, and these init.d style scripts aren't the natural mechanism anymore. Maybe this is SELinux related?

Update

JAVA_HOME should be defined, as I previously ran:

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.171-8.b10.el7_5.x86_64/jre

sudo sh -c "echo export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.171-8.b10.el7_5.x86_64/jre >> /etc/environment"     

… I tested and confirmed that is resolving in this context.
