[SNMP4J] help: multiple context

[Liu, Yu M. (NSB - CN/Beijing)]

Hi experts,

We are using Snmp4J to develop our Subagent. Recently, we need to support multiple context function in our subagent and we follow below reference to achieve that.
https://doc.snmp.app/pages/viewpage.action?pageId=14155780

But in our testing, we observe that when we configure context "contexta" and ""(empty) together, then snmpwalk context "contexta" MIB table, it will get some OIDs from context ""(empty) MIB table.
Below is an example, the id "60" and "61" belong to context "contexta", id "64" and "65" belong to context ""(empty).
[root@ ~]# snmpwalk -n contexta -v 3 -u test1 -a MD5 -A 12345678 -x DES -X 12345678 -l authPriv 10.76.84.132:31101 1.3.6.1.4.1.94.7.1.4.2.1
SNMPv2-SMI::enterprises.94.7.1.4.2.1.1.60 = INTEGER: 60
SNMPv2-SMI::enterprises.94.7.1.4.2.1.1.61 = INTEGER: 61
SNMPv2-SMI::enterprises.94.7.1.4.2.1.2.60 = STRING: "system-system-test/host-host/container-container/service-service/process-process"
SNMPv2-SMI::enterprises.94.7.1.4.2.1.2.61 = STRING: "system-system-test/host-host/container-container/service-service/process-process"
SNMPv2-SMI::enterprises.94.7.1.4.2.1.3.60 = Hex-STRING: 07 E2 02 0A 01 24 21 00 2D 00 00
SNMPv2-SMI::enterprises.94.7.1.4.2.1.3.61 = Hex-STRING: 07 E2 02 0A 01 24 21 00 2D 00 00
SNMPv2-SMI::enterprises.94.7.1.4.2.1.4.60 = INTEGER: 600033
SNMPv2-SMI::enterprises.94.7.1.4.2.1.4.61 = INTEGER: 600034
...
SNMPv2-SMI::enterprises.94.7.1.4.2.1.20.64 = ""
SNMPv2-SMI::enterprises.94.7.1.4.2.1.20.65 = ""


Would you please help to check if it's normal. Thanks!
