private void jButton4ActionPerformed(java.awt.event.ActionEvent evt) {                                         
        // TODO add your handling code here:
        DefaultTableModel tm= (DefaultTableModel) jTable1.getModel();

    for (int i=0;i<tm.getRowCount();i++) {
          Boolean checked=(Boolean)model.getValueAt(i,0);
          if (checked!=null && checked) {
               tm.removeRow(i);
               i--;
          }
    }
    }

that's because if combobox isn't selected you will get null not false.to avoid this you can check null or not first

DefaultTableModel model = (DefaultTableModel) jTable2.getModel();

    for (int i=0;i<model.getRowCount();i++) {
          Boolean checked=(Boolean)model.getValueAt(i,7);
          if (checked!=null && checked) {
               model.removeRow(i);
               i--;
          }
    }

Try to iterate in a descent way:

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {                                                    
    DefaultTableModel model = (DefaultTableModel) jTable2.getModel();
    for (int i=model.getRowCount();i<0;i--) {
          Boolean checked=(Boolean)model.getValueAt(i-1,7); // Checkbox is in 7th column?
          if (checked) {
               model.removeRow(i-1);
          }
    }
}
