ConfigurationFactory requires '{}' for keys when no configuration is present

[jack-berg]

Suppose you want to configure the console exporter using file configuration. You might have a configuration like:

tracer_provider:
  processors:
    - batch:
         exporter:
           console:

But this wont work. For the reason described here, you need to configure console with an empty object {}:

tracer_provider:
  processors:
    - batch:
         exporter:
           console: {}

This is inconvenient, error prone, and surprising. Investigate jackson configuration options to see if we can remove this requirement.
