Description

Steps to reproduce:

Start up OpenNMS with Trapd enabled (default case)
Send a trap with at least one octet-string varbind containing a series of characters that does not parse as UTF-8 text. The sequence 4f5ffa95 in the following command serves as an example:

snmptrap -v1 -c public 127.0.0.1 \
 .1.3.6.1.4.1.9.9.5.34 10.20.30.40 5 0 '' \
 .1.3.6.1.4.1.9.9.131.1.5.2.0 i 1 \
 .1.3.6.1.4.1.9.9.131.1.5.3.0 x 4f5ffa95

Expected result: Trap ingested silently and turned into an event

Actual result: No event is created, and the following appears in trapd.log:
