Regression bug in TreeView.getSelectionModel().getSelectedItem()

[Abu Abdullah]

Hi,

I have old application on jfx bundled with oracle jdk 1.8 working fine.

i have upgraded it to the latest jfx14 but found the following issue:

TreeView.getSelectionModel().getSelectedItem() returns null eventhough that
TreeView.getSelectionModel().getSelectedItems().size() = 1

code is like:
*********************************
TreeView.getSelectionModel().getSelectedItems().
addListener(new ListChangeListener<TreeItem<AudioInfo>>()
{
@Override
public void onChanged(Change<? extends TreeItem<AudioInfo>> change)
{
int i = TreeView.getSelectionModel().getSelectedItems().size();
// i =1

TreeItem<AudioInfo> node = TreeView.getSelectionModel().getSelectedItem();
// node = null
}
});
************************************

in the bundled version of jfx, it was working as expected and im able to
retrieve the object.
