  simply returns the expression itself as the resolved value, which adds
  very little value to the container. Things like ${project.build.resources}
  are not resolved, and result in a type mismatch for the member injection.

  We need a replacement for DefaultExpressionEvaluator that is capable of
  traversing an object graph and extracting Object values, not just Strings.
