james ahlborn commented on MRM-719:
-----------------------------------
Also note that the code where this is throwing is actually within a catch
block, presumably trying to get the logger. the other disturbing bit about
this code, is that it is not outputting any info about the actual
ConsumerException being thrown, which will make it rather hard to debug other
consumer issues. e.g. something is causing a ConsumerException, which is
leading to the NPE while logging, but the underlying cause is being lost.
