> SystemPropertiesPropertySource.forEach(..) uses Property.getProperty(..)
> to resolve values. If that value is a non-String, the value will be
> null. Since {{literal}} is a ConcurrentHashMap, a put(..) with null value
> will yield a NullPointerException.
> This is especially hard to debug in the case of e.g. StatusLogger,
> which initializes PropertiesUtil as a static variable. The class is
> unable to load, throws a NoClassDefFoundError, and hides the
> NullPointerException.
> Here's what I got when I had a Property value that was a File:
> Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.apache.logging.log4j.util.PropertiesUtil
> at org.apache.logging.log4j.status.StatusLogger.(StatusLogger.java:78)
> at org.apache.logging.log4j.LogManager.(LogManager.java:60)
