> AggregatedLogFormat.LogValue.write() currently has a bug where it only writes in blocks of the buffer size (65535). This is because FileInputStream.read(byte[] buf) returns -1 if there are less than buf.length bytes remaining. In cases where the file size is not an exact multiple of 65535 bytes, the remaining bytes are truncated.
