The statement "return -1 if the end of the stream has been reached and len ==
0" gives an impression that it requires both conditions to be met: end of the
stream && len==0, but the tests show -1 is expected if len == 0 without an
attempt to read the stream.
The overridden method stated that "If len is zero, then no bytes are read and 0
is returned", the above note looks like was meant for this statement since the
overridden method also return -1 if the stream is at end of file.
