While accidentally doing horrible things with hasPathOrNull(String), I managed to pass an empty string. The error message said, in part:
com.typesafe.config.ConfigException$BadPath: path parameter: Invalid path '': path has a leading, trailing, or two adjacent period '.' (use quoted "" empty string if you want an empty element)
I assume that indeed an empty string should be a problem (though it could be used to return the thing itself), but this error message momentarily confused me.
