Sorry, my previous reply was completely wrong. The time is initialized through the initialize() to 0. So, each time i call main() the simulation time is initialized to 0.

I changed the code in order to print and check the values of 

G.Rnd.expovariate(MachineClass.SrvRate) and G.Rnd.expovariate(ArrivalClass.ArvRate)

here is the code and the changes i made : http://codeviewer.org/view/code:30d8

The values are not the same.

The result i take is the following:

Result from main() call No. 1 is 0.0452927906737
Result from main() call No. 2 is 0.0588336669949
