[SNMP4J] IllegalArgumentException: MPv3 only accepts ScopedPDU instances as pdu parameter

[Glenn Gerhardt (glgerhar)]

Frank, 
I implemented the fix you suggested on July 22 for getting past the
NullPointerException 
when doing v3 proxy.  I am now getting past the previous exception, but
I am 
now getting an IllegalArgumentException later on.

 Exception in thread "RequestPool.0" java.lang.IllegalArgumentException:
MPv3 only accepts ScopedPDU instances as pdu parameter
	at org.snmp4j.mp.MPv3.prepareOutgoingMessage(MPv3.java:575)

org.snmp4j.util.ThreadPool$TaskManager.run(ThreadPool.java:238)

This is occuring when the request reaches the agent as a v2c packet, and
is then to be  
proxied to a v3 agent.  Any suggestions for a fix to this?
 
Thanks, Glenn
