Ensuring org.slf4j.helpers.MessageFormatter.arrayFormat() in

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.

java.lang.AssertionError: java.lang.NoSuchMethodError: 
org.slf4j.helpers.MessageFormatter.arrayFormat(Ljava/lang/String;[Ljava/lang/Object;)Lorg/slf4j/helpers/FormattingTuple;

Suggestions? Rules of thumb?

Thanks.

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.
