Unable to get Applescript Engine on some computers

From what I understand from working with the service loader framework in general if the relevant config file is present on the classpath, either loose as a file or in any jar it will be used. 

The file would be META-INF/services/something. 

Given that jar is in the extensions directory I think it will be loaded regardless of name. Try moving it to another folder temporarily?
