Is there a way to add a spacer node to a JTree?

For example:

Root
|
+--- Child 1
|
+--- Child 2
|
+--- child 3

I want it to show up as

Root
|
+--- Child 1
|
| << Empty space here >>
|
+--- Child 2
|
+--- child 3

I can always add an empty node but the display doesn't look correct.
Looks something like this.

Root
|
+--- Child 1
|
+---  << empty node >>
|
+--- Child 2
|
+--- child 3

Notice the connecting lines. I know I can turn off the lines but I was
looking for another way. Any ideas?
