Here's a full example of what I see when I run a unit test. In my root
/pom.xml/, I'm forcing a dependency of /slf4j-api/ and /slf4-simple/,
version 1.7.25, to ensure what's there isn't something old offered by
another dependency. Any suggestion would be welcome.

I'm struggling to figure out how to respond to this problem of
ensuring the presence of MessageFormatter(), which I think is in
/slf4j-simple-x.y.z.jar/, and/or ensuring the log4j system is properly
initialized. The need for slf4j is clearly coming from NiFi; I only
need it because it's a dependency in NiFi. I know there are problems
with slf4j version mixtures and I'm trying not to do anything else but
allow NiFi to cause the right version to get pulled in.
When I run some of my unit tests, I'm seeing this:
log4j:WARN No appenders could be found for logger
(com.imatsolutions.nifi.processor.filter.LegacyFullDocSearchReplaceFilter).
log4j:WARN Please initialize the log4j system properly.
