org.apache.logging.log4j.core.impl.ContextDataFactory.<clinit>(ContextDataFactory.java:49)
... 77 more{code}
It seems that JMX is looking up a property that references Spring and it is
trying to log something right after the configuration has been stored. It then
tries to initialize ContextDataFactory but once again needs to look up a
property and once again that tries to lookup a property. So the end result is
that it finally ends up with an uninitialized ContextDataFactory and gets the
NPE.

> First of all I have no idea what is missing. Without mentioned dependency
> application startup is correct. Also, removing DynamicThresholdFilter solves
> the problem as well.
> Second of all it seems that exception message is somewhat broken, because it
> does not say anything about what class is missing. I've tried to debug this,
> but class ContextDataFactory is pretty hard to debug. Fix in exception
> message should ease the hunt.
