Unable to get Java 8 generated keystore to be recognized by Jenkins 2.101 (Winstone)?

[Rob Gordon]

I'm having some difficulty enabling SSL on my Jenkins server (build 2.101 on CentOS 7.x).

I have generated a Java keystore, using jks format, and the keystore is

The only variable in the keystore that's 'unique' is the keystore alias variable.  And I'm not seeing anywhere in the /etc/sysconfig/jenkins configuration file where I can define the keystore alias variable, as I've been able to do with other Tomcat server applications.   When I attempt to start Jenkins (installed a a service) I receive the following error message.   The path is definitely correct and all appropriate permissions are applied to the keystore.

Does Winstone usually look for a specific "default" alias in a keystore, and is there a JAVA variable that can be issued in the configuration file to define the alias variable?
