      Description

      FULL PRODUCT VERSION :
      Newest jdk-9.

      A DESCRIPTION OF THE PROBLEM :
      When we add the children into the FXML file then it needs id of an element whether it will be used by developer or not.
      For eg:
       <children>
                     <fx:include fx:id="notepadPlus" source="NotepadPlus.fxml" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0" />
                 </children>

      /* without fx:id the code generates error*/

      REGRESSION. Last worked in version 9.0.4

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Create FXML file that include another FXML layout.
      2. <children>
                     <fx:include source="NotepadPlus.fxml" />
                 </children>
      3. Include above code.
      4. source represents another FXML file.
