The IO classes are the weakest part of Java and are largely a joke since it's excessively constrained to a very strict OOP model. This has the tendency to over constrain programming concepts to an oversimplicistic view of IO, therefore crippling Java in this area.
This might be helpful:

I might be incorrect since I don't track Java any more, but they are just moving to a select()/poll() IO model now, which is fairly pathetic IMO.
Java in general is an under appreciate technology for it's OOP cleanliness and modularity, but horribly incomplete in many areas.
