When including a changeLog from another changeLog, if the file does not exist, the error is less than helpful:

This can result in a lot of work to track down which file was referenced with an incorrect path and from where.

At a minimum, this should be caught because changeLogStream will be null YamlChangeLogParser.java:61, so throwing an exception there that identified that bad path would be helpful.

Even better would be identifying the file that contains the invalid include.
