hocon object merging (inheritance) behavior not expected

[gengle]

 Feature: HOCON Configuration
  Scenario: new objects can support inheritence via object merging
  Given I have hocon  
  ###
  data-center-generic = { cluster-size = 6 }
  data-center-east = ${data-center-generic} { name = "east" }
  ###
  When I parse hocon
  Then I should have the following values
      | path                             | value | 
      | data-center-generic.cluster-size | 6     | 
      | data-center-east.cluster-size    | 6     | 
      | data-center-east.name            | east  | 

data-center-east.cluster-size returns null
