[Bug in v 0.3.0] java.lang.NullPointerException: null

[sonnylaskar]

Hi,

I am using Graylog v2.3 and installed the plugin version 0.3.0 on CentOs 6.6
I downloaded the VMWare MIB files as mentioned in the README file.

I have only 1 MIB file:
/usr/share/mibs/1/VMWARE-ROOT-MIB.mib

When I start Graylog and start sending Snmp traps, I get the below error:

2017-08-03T18:48:18.130+05:30 ERROR [SnmpMibsLoader] Error loading MIB file: /usr/share/mibs/1/VMWARE-ROOT-MIB.mib

@sonnylaskar Please attach the MIB file.

[sonnylaskar]

I cleaned up everything to ensure that I have only 1 MIB file.
Now Error is about IndexOutOfBounds:
