Hi, I downloaded the source code and I think I have found the problem. 
It seems that the SelectorFactory class has been unloaded for some reason. 

After checking the implementation for SelectorFactory, it is not guaranteed 
that the SelectorFactory class has been loaded, so a Singleton implementation 
with eager instantiation should avoid the problem.
