Non-blocking Vectored read from SocketChannel fails

Question

Hi.
Please look at the code example:
ByteBuffer tmp1 = ByteBuffer.allocate(500);
ByteBuffer tmp2 = ByteBuffer.allocate(500);
ByteBuffer[] tmp = {tmp1, tmp2};
while ((count = socketChannel.read(tmp)) > 0) {
+ "bytes.");
When I run this code, (using non-blocking socket channel), the first buffer is read ok, but on the second round of the while loop, I get an IOException, saying: "a non blocking socket operation could not be completed immediately".
If I put 'tmp1' instead of 'tmp' in the read(), (i.e - use a normal buffer), the read successfully finishes.
Why?
I found nothing in the documentation, and in the 'Java NIO' book (Ron Hitchens).
Help?
Thanks.

Please ignore the + "bytes."); inside the while.
