I monitor the layoutContainer() method and I notice that it gets called

calling layoutContainer()?

I'm not sure what you mean here. Could you post some code? I wrote a
custom layout as a test and it seems to all get called correctly, so I
don't know what your issue could be.

Here's my set up:

   SwingUtilities.invokeLater( new Runnable() {

       public void run()
       {
           JFrame frame = new JFrame( "Test" );
           LayoutManager lm = new CustomLayout();
           frame.setLayout( lm );
           JPanel panel = new JPanel();
           panel.add( new JButton("A") );
           panel.add( new JButton("BBBBBBBBB") );
           frame.add( panel );
           frame.pack();
           frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
           frame.setLocationRelativeTo( null );
           frame.setVisible( true );
       }
   } );
