Buggy source:
private void setupActionPanel(){
  this.actionPanel.setLayout(new GridBagLayout());
  GridBagConstraints c=new GridBagConstraints();
  this.actionPanel.setPreferredSize(new Dimension(600,100));
  c.gridx=0;
  c.gridy=0;
  irrelevantCheckBox=addCheckBox("String_Node_Str",c);
  c.gridx=1;
  c.gridy=0;
  focusCheckBox=addCheckBox("String_Node_Str",c);
  c.gridx=0;
  c.gridy=1;
  interactingNodeCheckBox=addCheckBox("String_Node_Str",c);
  irrelevantCheckBox.addChangeListener(this.irrelevantCheckBoxListener);
  focusCheckBox.addChangeListener(this.focusCheckBoxListener);
  interactingNodeCheckBox.addChangeListener(this.interactingNodeCheckBoxListener);
  prevButton=new JButton("String_Node_Str");
  c.gridx=0;
  c.gridy=2;
  this.actionPanel.add(prevButton,c);
  prevButton.addActionListener(this.prevActionListener);
  nextButton=new JButton("String_Node_Str");
  c.gridx=1;
  c.gridy=2;
  this.actionPanel.add(nextButton,c);
  nextButton.addActionListener(this.nextActionListener);
  acceptButton=new JButton("String_Node_Str");
  c.gridx=1;
  c.gridy=1;
  this.actionPanel.add(acceptButton,c);
  acceptButton.addActionListener(new ActionListener(){
    @Override public void actionPerformed(    ActionEvent e){
      currentSentence.sentenceValidated();
      int currSelectionIdx=getCurrentSelection();
      if (getCurrentSelection() < tableModel.getRowCount() - 1) {
        currSelectionIdx++;
      }
      selectionModel.setSelectionInterval(currSelectionIdx,currSelectionIdx);
      int scrollOffset=dataViewTable.getRowHeight() * getCurrentSelection();
      dataViewScrollPane.getVerticalScrollBar().setValue(scrollOffset);
    }
  }
);
}

Fixed version (ground truth):
private void setupActionPanel(){
  this.actionPanel.setLayout(new GridBagLayout());
  GridBagConstraints c=new GridBagConstraints();
  this.actionPanel.setPreferredSize(new Dimension(600,100));
  c.gridx=0;
  c.gridy=0;
  irrelevantCheckBox=addCheckBox("String_Node_Str",c);
  c.gridx=1;
  c.gridy=0;
  focusCheckBox=addCheckBox("String_Node_Str",c);
  c.gridx=0;
  c.gridy=1;
  interactingNodeCheckBox=addCheckBox("String_Node_Str",c);
  irrelevantCheckBox.addChangeListener(this.irrelevantCheckBoxListener);
  focusCheckBox.addChangeListener(this.focusCheckBoxListener);
  interactingNodeCheckBox.addChangeListener(this.interactingNodeCheckBoxListener);
  prevButton=new JButton("String_Node_Str");
  c.gridx=0;
  c.gridy=2;
  this.actionPanel.add(prevButton,c);
  prevButton.addActionListener(this.prevActionListener);
  nextButton=new JButton("String_Node_Str");
  c.gridx=1;
  c.gridy=2;
  this.actionPanel.add(nextButton,c);
  nextButton.addActionListener(this.nextActionListener);
  acceptButton=new JButton("String_Node_Str");
  c.gridx=1;
  c.gridy=1;
  this.actionPanel.add(acceptButton,c);
  acceptButton.addActionListener(new ActionListener(){
    @Override public void actionPerformed(    ActionEvent e){
      currentSentence.sentenceValidated();
      int currSelectionIdx=getCurrentSelection();
      if (getCurrentSelection() < tableModel.getRowCount() - 1) {
        currSelectionIdx++;
      }
      selectionModel.setSelectionInterval(currSelectionIdx,currSelectionIdx);
    }
