Question regarding console INFO message from platform application

[Joseph Huber <JH...@stanref.com>]

Hello!

I have a Netbeans 8.2 platform application with just over 20 modules.  Whenever the program starts (run or debug), I see the message down below in the console output.  I have done numerous cleans/builds, looked through the various properties and xml files for that module, and I can't seem to figure out what the issue is.  The module successfully builds without any errors.   All the modules have updates centers, and there are no other such messages when the application starts.

So, what does the INFO message mean exactly regarding the update center in question?  I'm trying to figure out if this is a serious issue or something that can be ignored.

Any suggestions on how to trouble shoot this?
