Hi Pierre,
You can avoid this exception if you cancel all pending requests before
you close
the Snmp session.
I agree, that the Snmp.close() should do this for you. I will provide a fix
for it in version 2.2.3.
Best regards,
Frank

Hi,
I'm using SNMP4J and I'm sometime getting an NPE in pduHandleAssigned :
java.lang.NullPointerException
at org.snmp4j.Snmp$PendingRequest.pduHandleAssigned(Snmp.java:1624)
at org.snmp4j.Snmp$PendingRequest.pduHandleAssigned(Snmp.java:1485)
at org.snmp4j.MessageDispatcherImpl.sendPdu(MessageDispatcherImpl.java:495)
at org.snmp4j.Snmp.sendMessage(Snmp.java:1005)
at org.snmp4j.Snmp$PendingRequest.run(Snmp.java:1666)
at java.util.Timer$TimerImpl.run(Timer.java:284)
Given that the line 1624 is : "timer.schedule(this, delay);" , I assume the
timer is null.
It might be that this happens when closing SNMP4J with an ongoing PendingRequest (in
close(), line 509, timer is set to null) but I'm unfortunately not able to confirm this
assumption : the problem only happens "on the field" and I never reproduce it
in debug.
In can upgrade to 2.2.2, but I don't see any relevant difference in the
(potentially offending) code.
Do you have any idea of what I could do investigate this issue ?
thanks a lot for the good work,
Pierre Rust
