ConcurrentLinkedQueue remove(Object o) always fails in ActionListener?

Question

Hi,
I tried to write a tiny program where if I click a button, the right String is removed from a ConcurrentLinkedQueue.
However, it doesn't work at all. To troubleshoot, I tried other ConcurrentLinkedQueue methods such as add(), offer(), remove(void). They all work fine except remove(Object o).
According to doc, remove(Object o) works if o.equals(e). So I also overwrote equals(Object o). It still doesn't work.
This is a pesudo code:
class a extends JFrame
public ConcurrentLinkedQueue<String> queue;
public JTextField text;
public JButton button;
public ActionListener removeAction=new ActionListener()
public void actionPerformed(ActionEvent e)
//Supposing it's string "StringA" in the text box GUI.
queue.remove(text.getText());
//false. Can't remove String "StringA" from queue.
public a()
queue.add("StringA");
queue.add("StringB");
queue.add("StringC");
add(text);
add(button);
button.addActionListener(removeAction);
Can anyone help me with it?

Possibilities:
1) There's a huge glaring bug in a significant public method that's been in general use for several years and you're the first one to find it.
2) There's a huge glaring bug in a significant public method that's been in general use for several years and others have found it before, but nobody bothered to fix it.
3) There's something wrong with your equals method.
4) There's something wrong with the code where you call remove.
5) There's something wrong with how you're determining that the object has not been removed.
