Ah, I should have read further in the Java doc here, though, before posting. In particular, the last sentence of this paragraph: "If the length of b is zero, then no bytes are read and 0 is returned; otherwise, there is an attempt to read at least one byte. If no byte is available because the stream is at the end of the file, the value -1 is returned; otherwise, at least one byte is read and stored into b."
https://docs.oracle.com/javase/8/docs/api/java/io/InputStream.html#read-byte:A- If implementations actually follow that documentation, then it appears that a non-0 buffer size should never result in a return value of 0.
