Duplicate jobs in solution when using initial routes in a XML vrp problem

[damariei]

If you add a service or shipment such as:

<service id="1">
  <coord x="2" y="2"/>
  <capacity-dimensions>
    <dimension index="0">0</dimension>
  </capacity-dimensions>
</service>

And use an initial route such as:

<initialRoutes>
          <route>
               <driverId>noDriver</driverId>
               <vehicleId>1</vehicleId>
               <start>0.0</start>
               <act type="service">
                    <serviceId>1</serviceId>
               </act>
               <end/>
        </route>
</initialRoutes>

The solution duplicates the job:

<solutions>
          <solution>
               <cost>16131.119189371566</cost>
               <routes>
                    <route>
                         <driverId>noDriver</driverId>
                         <vehicleId>1</vehicleId>
                         <start>0.0</start>
                         <act type="service">
                              <serviceId>1</serviceId>
                              <arrTime>4096.696026182618</arrTime>
                              <endTime>4096.696026182618</endTime>
                         </act>
                         <act type="service">
                              <serviceId>1</serviceId>
                              <arrTime>4096.696026182618</arrTime>
                              <endTime>4096.696026182618</endTime>
                         </act>
                         <end>4591.722277748453</end>
                    </route>
               </routes>
          </solution>

This doesn't happen if you remove the initial routes.

[damariei]

After some more testing, the only jobs that get duplicated are ones that are not in the initial routes.
For example, you have service A and B, and only A is defined in an initial route.
In the solution you will see B getting done twice. Putting B inside the initial route as well removes this issue.

Either way jobs should not appear twice in solution. I will be looking at this asap.
