[IO] Provenance of copied code in InfiniteCircularInputStream

[Gary Gregory]

Hi All and Pascal S.,

Sharon (Eclipse) has pointed out to me that
in org.apache.commons.io.input.InfiniteCircularInputStream.read() [1], we
have:

    @Override
    public int read() {
        position = (position + 1) % repeatedContent.length;
        return repeatedContent[position] & 0xff; // copied from
                                                 //
java.io.ByteArrayInputStream.read()
    }

Where does the code originate? Oracle JRE? OpenJDK? Where? Such a comment
needs to show better provenance since I am pretty sure we are NOT allowed
to copy code from Oracle.

The code was added with the commit
