Not possible to activate DEBUG trace for SNMP Binding

Hi,

I’m using OH 3.3.0M5 in a docker installation environment.
Today I tried to setup the SNMP binding to observe my NAS.
The SNMPWALK from the host itself is working correctly.
Unfortunately in OH the channel says UNDEF.
The openhab.log show this:

20:16:32.388 [INFO ] [nding.snmp.internal.SnmpTargetHandler] - SNMP Exception: request 1.3.6.1.4.1.6574.1.2 returned 'noSuchInstance'

Therefore I tried to increase the tracelevel to DEBUG:

openhab> log:set DEBUG org.openhab.binding.snmp

but the output in the logfiles is still [INFO].
Is it a regression in 3.3.0.M5 or do I need another DEBUG setting?
Thanks for your feedback!
