If you use the read(byte[], int, int) method of BufferedInputStream, the number of bytes read might be less than you requested (even if that many of more bytes are still unread in the file).

(Presumably, the buffer in memory was emptied with the read, and Java only returns the number of bytes left in the buffer)

EVALUATION Not a bug. Java is not Unix: The JLS allows this behavior.

WORK AROUND Name: mc57594 Date: 02/07/97 Check if you read the number of bytes you requested. If you read less than you requested and available() > 0, then perform another read to get the remaining bytes. ======================================================================
