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. ------------- PR: https://git.openjdk.java.net/jdk17/pull/189
