No, no, no. It's not dangerous at all
In the post the guy says "... if not would it be an automatic failure.", but he's actually asking (he used . instead of ? after the phrase!). What needs to happen is, this file is NOT included in the final .jar file. This file is generated in the same working directory of the application. In my case, I used the suncertify.properties file to store all properties of the 3 modes. In standalone mode, I just ask for the .db file location. In server mode, I ask for the .db file location and in which port the server will run. In client mode, I ask for the server IP address and the port in which the server is running.
Take a look at
this thread. I think it might be helpful!
