The following calls to deprecated methods (see JDK-8270314) were added as part of the fix to JDK-8188026:

modules/javafx.controls/src/test/java/test/javafx/scene/control/cell/TreeTableCellStartEditTest.java:
   109 treeTableCell.updateTreeTableColumn((TreeTableColumn) treeTableColumn);
   110 treeTableCell.updateTreeTableRow(treeTableRow);

They should be replaced with calls to updateTableColumn and updateTableRow, respectively.
