title: Column of GroupLayout is Unaligned
body: <p>The leftmost column is what I'm referencing here:</p>

  <p>About a week ago, I convinced my dad to ditch Windows 10 in favor of Linux Mint. The transition's been quite bumpy so far, considering how he likes to have a simplistic interface. He's not willing to work with the command line, so I've spent the better half of the day trying to make a java user interface so he'll quit his nagging on how he can't run a script. I do want it perfect, though, and this misalignment is annoying the heck out of me. I honestly don't understand what's different about that column compared to the others.</p>
  
  <p>Here's my format method, which does all the GroupLayout stuff</p>
  
  <pre><code>    private void format() {
      GroupLayout layout = new GroupLayout(getContentPane());
      getContentPane().setLayout(layout);
      layout.setAutoCreateGaps(true);
      layout.setAutoCreateContainerGaps(true);
  
      layout.setHorizontalGroup(layout.createSequentialGroup()
              .addGroup(layout.createParallelGroup(LEADING))
                  .addComponent(inputLabel)
                  .addComponent(outputLabel)
                  .addComponent(exitButton)
              .addGroup(layout.createParallelGroup(LEADING)
                      .addComponent(inputTextField, 300, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
                      .addComponent(outputTextField, 300, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
                      )
              .addGroup(layout.createParallelGroup(LEADING).addComponent(inputButton).addComponent(outputButton)
                      .addComponent(compressButton)));
  
      layout.linkSize(SwingConstants.HORIZONTAL, inputButton, outputButton);
  
      layout.setVerticalGroup(layout.createSequentialGroup()
              .addGroup(layout.createParallelGroup(LEADING)
                      .addComponent(inputLabel)
                      .addComponent(inputTextField, 0, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
                      .addComponent(inputButton))
              .addGroup(layout.createParallelGroup(LEADING)
                      .addComponent(outputLabel)
                      .addComponent(outputTextField, 0, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
                      .addComponent(outputButton))
              .addGroup(layout.createParallelGroup(LEADING)
                      .addComponent(exitButton)
                      .addComponent(compressButton)));
  
      setTitle("PDF CONVERTER");
      pack();
      setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
  }
  </code></pre>
  
  <p>Any help would be much appreciated. Thanks in advance!</p>
