“AWT-EventQueue-0” java.lang.StackOverflowError - While trying to create JTree folder structure

I'm trying to build a JTree folder structure from a output. Here is the approach.

JTree

This is working fine when the number of folders are less however when the number of folders are more it is throwing a stack overflow error.

private static DefaultMutableTreeNode builtTreeNode(String comptype) {
try
List<Node> nodeList = new ArrayList<>();
//Defin the configuration context
APIObject fol = //Call the other system to get folders;
DefaultMutableTreeNode dmtNode = null;
System.out.println(" Folder Size " +fol.length);
for (int i = 0; i < fol.length; i++)
if(getParentFolder().getName() == null && !getParentFolder().getIsActive())
dmtNode = new DefaultMutableTreeNode(df.getName().toString());
nodeList.add(new Node(df.getName().toString()));// Set the ROOT folder in nodelist

if(getParentFolder().getName() != null )
//nodeList.add(new Node("Child", "Parent"));
//add remaining folders to nodelist
nodeList.add(new Node(df.getName(), df.getParentFolder().getName()));


findChild(dmtNode, nodeList); //
return dmtNode;

private static void findChild(DefaultMutableTreeNode parent, List<Node> list)
for (int i = 0; i < list.size(); i++)
if (list.get(i).parent != null && list.get(i).parent.equals(parent.toString()))
DefaultMutableTreeNode child = new DefaultMutableTreeNode();
child = new DefaultMutableTreeNode(list.get(i).label);
parent.add(child); // Getting exception from this line of code
findChild(child, list); // child of child
