[SNMP4J] SNMP4j drops traps throwing an exception, but trap is valid and properly processed by other applications

[Chatterjee, Soumya Subhra]

Hi Frank,
There is one more issue with SNMP4j (I think). There is another trap, which is dropped by SNMP4j with the log entry: 2013-10-19 15:20:03,856 WARN  [DefaultUDPTransportMapping_0.0.0.0/162] snmp4j.MessageDispatcherImpl - java.io.IOException: Only 32bit unsigned integers are supported at position 48. 

But in other applications, including when it is captured and opened in Wireshark, it works fine and all the data is available. I am attaching the hex dump here. If needed, I can provide code snippets and Wireshark captures also.

Trap data: 30:82:01:84:02:01:00:04:06:70:75:62:6C:69:63:A4:82:01:75:06:0C:2B:06:
