It fails because some singletons are used and AFAIK there is no clean way to
reset the variables. I also use an external script to execute the whole thing
several times (as some people has advised you).

But for instance Alea (a package based on GridSim for testing scheduling
algorithms) uses a modified simjava package that implements a method that resets
these inner variables.

Furthermore, if you are using another GIS (such as DataGIS), you will also need
to reset it, and the method setGIS is not enough, you need to "unsetGIS" first.
But this method is not implemented, so I coded it in GridSim class:

public static boolean unsetGIS()
{
    gis_ = null;
    return true;
}

That's all
