org.dcm4che3.mime.MultipartInputStream - wrong byte to int conversion on read()

[navrkalpavel]

The method org.dcm4che3.mime.MultipartInputStream.read() incorrectly handles byte to int conversion:

public int read() throws IOException {
       return isBoundary() ? -1 : buffer[rpos++];
}

The right conversion is:

public int read() throws IOException {
        return isBoundary() ? -1 : (buffer[rpos++] & 0xff);
}
