Max size for bytea type

Hello,

Can someone explain why I cann't get bytea data of more than 1998 bytes?
Below 1998 size is ok but I got exception if the size is at and above
1998. I used jdbc-8.1-407.jdbc3.jar.

//setting bytea value. Work fine
byte[] bdata = new byte[1998];
for (int b = 0; b < bdata.length; b++) {
bdata[b] = (byte) (b % Byte.MAX_VALUE);
}

ByteArrayInputStream is = new
ByteArrayInputStream(bdata);

prepstmt.setBinaryStream(1, is, bdata.length);

//getting bytea value. Got error
ByteArrayInputStream s = (ByteArrayInputStream) rs
.getBinaryStream(1);

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException:
1998

Thanks
