[SNMP4J] Timer already cancelled exception

[Marco Matchefts]

I am using the async interface to send an SNMP Get request to an agent.
The request is

over UDP and using Version 2c.  The application invoking the async
interface is multithreaded.

I am getting an IllegalStateException in the stack saying the "Timer
already cancelled".

 

The stack trace is enclosed.  Any ideas?  Has anyone seen this before?
thanks in advance.

 

java.lang.IllegalStateException: Timer already cancelled.
