When the portal is starting the upgrade command, which is executed as part of the the module's startup checks prints to STDOUT, which is unwanted.
This is because it's using System.out as it's means of sending output to the gogo shell.
However this is not the most ideal way to handle command outputs.
It's far better to have the command method return a String, a java.util.Formattable, or just any Object that has a useful `toString()`.
