Yes it is match the behavior, but both have a different specifications:
In the old methods there is a notion: "<p> If <code>len</code> is zero, 
then no bytes are read and <code>0</code> is returned;" but in the new 
method we have only one strong statement: "After the stream has been 
closed, these methods all throw {@code IOException}."
