A DESCRIPTION OF THE REQUEST :
Looks like the copyright tag is supposed to be read from the configuration and written to the Info.plis (in MacAppBuilder.java)t:

    data.put("DEPLOY_BUNDLE_COPYRIGHT",
            COPYRIGHT.fetchFrom(params) != null ? COPYRIGHT.fetchFrom(params) : "Unknown");
but it's not included in 'getAppBundleParameters()' defined in the same file, so the configuration does not affect to what is being written to the file.

Or this is how I interpret it - anyways, would be nice to be able to configure the Copyright that gets to the Info.plist as well.




JUSTIFICATION :
The copyright is visible in the default About box of the installed Swing applications in OSX, but is now a fixed string: "Copyright (C) 2017"
