"0" unit value reseting to "100.00" after reopening file about ganttproject HOT 6 CLOSED

I looked at this, was a bit confusing since it saves correctly and only 
triggers when
Unit is 0. It seems that when the project is loaded from file, in
AllocationTagHandler, it manually checks if the value is 0 and sets it to 100 :

// if no load is specified I assume 100% load
// this should only be the case if old files
// were loaded.
if (load == 0) {
    load = 100;
}

Arbitrarily changing saved data on load seems like a bad idea, I uploaded a 
patch to
the patch tracker on sourceforge that removes this "feature".
