Fixed in 1.10 branch

commit 9aceb11b92b7b5ab06da193140b8e4b269065951

FYI, there was code related to this still in 1.8 and up; we had to revert it because it was breaking collections and other things, it appears to be the code that is breaking https://opennms.atlassian.net/browse/NMS-4683#icft=NMS-4683.

We should design a better way to deal with this. Some of the refactoring in provisiond that Matt and I are working on might take care of some of these issues.

From a discussion with Ben:

Hm, ok. The goal in provisiond is to store as little state as possible,
so we're not filling memory with 20,000 nodes' data and such, I wonder
if there's another way to do this.

Here the hell comes...the trouble is that the information is how to say on two snmp table.

The trouble is that we apply a filter rule that cannot be applied onto snmpiftable ifTable just because
no ip address can be defined there.

The way in which we assign the ip address to OnmsSnmpInterface is merging IpInterface (snmp) table data using the interface index.

So my idea that to avoid maps we have to add a new node scan phase in which we can apply filter like that over snmpinterface using ipaddress: this phase is to be run after the OnmsIpInterface and OnmsSnmpInterfaces
have been discovered and persisted.

The idea would be then having another scan phase in which we use a merge "filter"....for example we can filter ipinterface using "snmp interface data"
and snmpinterface using "ipinterface data".

The changes that have been done are not acceptable

this has been fixed in 1.8
