Buggy source:
public ScreenInfoPanel(@Nonnull List<Screen> screens){
  imagePanel=new ImagePanel();
  viewTree=new JTree(new DefaultMutableTreeNode("String_Node_Str"));
  viewTree.getSelectionModel().setSelectionMode(TreeSelectionModel.SINGLE_TREE_SELECTION);
  viewTree.addTreeSelectionListener(this);
  JScrollPane treeScroller=new JScrollPane(viewTree);
  rootPicker=new JComboBox(new Vector<Object>(screens));
  rootPicker.addItemListener(this);
  JPanel settingsPanel=new JPanel(new GridLayout(1,2));
  showBoundsBox=new JCheckBox("String_Node_Str",true);
  showBoundsBox.addItemListener(this);
  forceAlpha=new JCheckBox("String_Node_Str",true);
  forceAlpha.addItemListener(this);
  settingsPanel.add(showBoundsBox);
  settingsPanel.add(forceAlpha);
  settingsPanel.setBorder(new EmptyBorder(10,0,0,0));
  infoTable=new JTable();
  infoTable.setRowSelectionAllowed(false);
  infoTable.setColumnSelectionAllowed(false);
  infoTable.setCellSelectionEnabled(false);
  infoTable.setShowGrid(true);
  JPanel bottomPanel=new JPanel(new BorderLayout());
  bottomPanel.setBorder(new EmptyBorder(10,10,10,10));

  JSplitPane splitPane=new JSplitPane(JSplitPane.HORIZONTAL_SPLIT);
  splitPane.setLeftComponent(leftPanel);

}

Fixed version (ground truth):
public ScreenInfoPanel(@Nonnull List<Screen> screens){
  super(new BorderLayout());
  imagePanel=new ImagePanel();
  viewTree=new JTree(new DefaultMutableTreeNode("String_Node_Str"));
  viewTree.getSelectionModel().setSelectionMode(TreeSelectionModel.SINGLE_TREE_SELECTION);
  viewTree.addTreeSelectionListener(this);
  JScrollPane treeScroller=new JScrollPane(viewTree);
  rootPicker=new JComboBox(new Vector<Object>(screens));
  rootPicker.addItemListener(this);
  JPanel settingsPanel=new JPanel(new GridLayout(1,2));
  showBoundsBox=new JCheckBox("String_Node_Str",true);
  showBoundsBox.addItemListener(this);
  forceAlpha=new JCheckBox("String_Node_Str",true);
  forceAlpha.addItemListener(this);
  settingsPanel.add(showBoundsBox);
  settingsPanel.add(forceAlpha);
  settingsPanel.setBorder(new EmptyBorder(10,0,0,0));
  infoTable=new JTable();
  infoTable.setRowSelectionAllowed(false);
  infoTable.setColumnSelectionAllowed(false);
  infoTable.setCellSelectionEnabled(false);
  infoTable.setShowGrid(true);
  JPanel bottomPanel=new JPanel(new BorderLayout());
  bottomPanel.setBorder(new EmptyBorder(10,10,10,10));
  bottomPanel.add(infoTable,BorderLayout.CENTER);
  bottomPanel.add(infoTable.getTableHeader(),BorderLayout.NORTH);
  bottomPanel.add(settingsPanel,BorderLayout.SOUTH);
  JPanel leftPanel=new JPanel(new BorderLayout());
  leftPanel.add(rootPicker,BorderLayout.NORTH);
  leftPanel.add(treeScroller,BorderLayout.CENTER);
  leftPanel.add(bottomPanel,BorderLayout.SOUTH);
  JSplitPane splitPane=new JSplitPane(JSplitPane.HORIZONTAL_SPLIT);
  splitPane.setLeftComponent(leftPanel);
