Regarding the Turbine Class

[Shiva Kumar T]

Hi,
I have few quetions regarding the Turbine.java class.

1.
In the init(ServletConfig config) method of turbine what is the need of synchronized  
block?
My quetion is if this is the startupServlet then this method will be called only once 
by the ServletEngine.Then what is the reason behind using this synchronized?

2.
In the above method synchronized has been put for threadsafe then again what is the 
need of the below code? Is n't it over cautious?

        if(!firstInit)
                {
                        log ("Double initializaton of Turbine was attempted!");
                    return;
                }


Thanx 
Shiva
