[SNMP4J] GetBulk returned with only one variable

[Lin, Dongliang]

Hello,
I tried asynchronous getBulk(see SNMP4J doc below) and got response PDU
with size is 1( only one variable in PDU).
However,   I can use "snmpbulkget" command in Linux to get the result
properly(multiple variables).  So I assume that Agent responds properly
on Getbulk.
I did notice that request pdu type being changed from GETBULK(originally
in snmp.getBulk(pdu, ,, )) into GETNEXT by examining response pdu in
onResponse()
Any help is much appreciated !
Thanks

	Asynchronously sends a GETBULK request PDU to the given target.
The response is then returned by calling the supplied ResponseListener
instance. 
Parameters: 
	pdu - the PDU instance to send. 
	target - the Target instance representing the target SNMP engine
where to send the pdu. 
	userHandle - an user defined handle that is returned when the
request is returned via the listener object. 
	listener - a ResponseListener instance that is called when pdu
is a confirmed PDU and the request is either answered or timed out. 
Throws: 
	java.io.IOException - if the PDU cannot be sent to the target.
