[SNMP4J] Issues implementing master agent

[Peder Toftegaard Olsen]

Hi,

RC2 of SNMP4J-AgentX has fixed my previously reported issues, but some new
ones popped up while creating a master agent to help me test the sub agent I
am implementing:


1) IllegalArgumentException when I try to unregister a previously registered
table row.

The exception is thrown in AgentXRegisterPDU because the constructor checks
the PDU's type. But since AgentXUnregisterPDU is a subclass of
AgentXRegisterPDU this check fails and results in an
IllegalArgumentException.

To get on with my work I removed the check in AgentXRegisterPDU.


2) Warning when unregistering.

2007-02-22 12:20:00,578 WARN  [org.snmp4j.agent.agentx.master.AgentXMib]
Registration has been removed that was not previously added to the
AgentXMib:

nID=1,byteOrder=null,timeout=5,consecutiveTimeouts=0,agentCaps=null]]

I don't know if this is correct, but I ended up copying the four lines of
code to calculate the index OID from the REGISTRATION_ADDED case.


3) NPE when deallocating an index.

Fixed by adding "vbs[i] = new VariableBinding()" to
AgentXSharedMOTableSupport.deallocateIndex(.).
