Hi there,
I am trying to develop an SNMP agent capable of responding to V1 and V2c
requests with the help of SNMP 4J Agent framework version 1.3.2;
my community string is configured as "public"; any time the agent
receives a V2c GET request with a community string different from
"public", it hangs and the following exception is logged:
20091202 173258 CET [ERROR] <DefaultUDPTransportMapping> PTMA0000:
java.lang.NullPointerException
Trace for the exception:
java.lang.NullPointerException
at java.util.TreeSet.<init>(TreeSet.java:154)

It does seem to me an actual SNMP 4J Agent framework issue...any help is
appreciated.
Kind regards
GL
