The method of class FixedHeightLayoutCache
public Rectangle getBounds(TreePath path, Rectangle placeIn) returns
the Rectangle with field 'width' == 0 always. Value for this field
should be calculated from the nodeDimensions specified previously.

The doc says:
--------------------------------------------------
public Rectangle getBounds(TreePath path,
                           Rectangle placeIn)

       Overrides:
              getBounds in class AbstractLayoutCache


// from AbstractLayoutCache class documentation //
public void setNodeDimensions(AbstractLayoutCache.NodeDimensions nd)

       Sets the renderer that is responsible for drawing nodes in the
       tree.

The test demonstrating the bug:
-----------------Test.java------------------------
import javax.swing.tree.*;
import java.awt.Rectangle;

public class Test {

    public static class DummyNodeDimensions extends AbstractLayoutCache.NodeDimensions {
private Rectangle rectangle;
public DummyNodeDimensions(Rectangle r) {
rectangle = r;
}
public Rectangle getNodeDimensions(Object value, int row,
int depth,
boolean expanded,
Rectangle bounds) {
return rectangle;
}
    }
    
    /* create the TreeModel of deep 1 with specified num of children */
    public static DefaultTreeModel getTreeModelILike(int childrenCount) {
        DefaultMutableTreeNode root =
            new DefaultMutableTreeNode("root");
        
        for (int i = 0; i < childrenCount; i++) {
            DefaultMutableTreeNode child =
                new DefaultMutableTreeNode("root.child"+i);
            root.insert(child,i);
        }
        return new DefaultTreeModel(root);
    }
   
    public static void main(String[] args) {
int x = 1, y = 2, dx = 3, dy = 4, h = 3;

DummyNodeDimensions dim = new DummyNodeDimensions(new Rectangle(x,y,dx,dy));

FixedHeightLayoutCache fhlc = new FixedHeightLayoutCache();
fhlc.setModel(getTreeModelILike(3));
fhlc.setRootVisible(true);
fhlc.setNodeDimensions(dim);
fhlc.setRowHeight(h);
int row = 0;
TreePath path = fhlc.getPathForRow(row);
System.out.println("path = "+path);


Rectangle r = fhlc.getBounds(path,new Rectangle());
Rectangle r2 = new Rectangle(x, row*h, dx, h);

System.out.println("r1="+r);
System.out.println("r2="+r2);
    }
}
---------Output from the test---------------------
path = [root]
r1=java.awt.Rectangle[x=1,y=0,width=0,height=3]
r2=java.awt.Rectangle[x=1,y=0,width=3,height=3]
