Using Ortool how to get route when we pass Start points without end points (using arbitrary concept)

[Pratibha-UID]

Could you please help me out where I am doing mistake, as I have followed the suggestion where I want to specify the start point and end should decided by algorithm for that I have tried same way which you mentioned in Allowing arbitrary start and end locations documentation but in result I am getting random start point and start point which I really expect at start that came at last location.

RoutingIndexManager(distancemetrix.length, numVehicles, new int[]{1}, new int[]{0});
numVehicles = 1

Below distance metrix I have passed.
Before :
{ {0, 972105, 889576, 968248, 987336, 883578, 934372},
{971997, 0, 95095, 5255, 17380, 99897, 68607},
{890190, 94882, 0, 92999, 108008, 6093, 59123},
{969866, 5273, 92964, 0, 17566, 97766, 66476},
{986885, 17967, 109983, 17203, 0, 114785, 83495},
{882710, 100256, 6953, 98734, 113743, 0, 64858},
{937247, 68597, 60345, 66714, 81723, 65147, 0}}

After adding arbitrary end point :
{ {0,0,0,0,0,0,0},
{0, 972105, 889576, 968248, 987336, 883578, 934372},
{0, 0, 95095, 5255, 17380, 99897, 68607},
{0, 94882, 0, 92999, 108008, 6093, 59123},
{0, 5273, 92964, 0, 17566, 97766, 66476},
{0, 17967, 109983, 17203, 0, 114785, 83495},
{0, 100256, 6953, 98734, 113743, 0, 64858},
{0, 68597, 60345, 66714, 81723, 65147, 0}}

Can anyone help on this where I am doing wrong?
