changing final Boolean value in SwingUtilities.invokeLater()

Hi,

I have a problem with setting final Boolean value in second time. But it is necessary to me. Have You any Idea of this Scenario?

Here is my code:

public static boolean doCommit()
{
  final boolean success = true;
  SwingUtilities.invokeLater(new Runnable()
  { 
    @Override
    public void run() 
    {                   
       success = "Hi".equals("Hai"); //for example, here, i am trying to calling my method and it says "The final local variable success cannot be assigned, since it is defined in an enclosing type"
    }               
  }); 
  return success;
}

Thanks,

Sekhar
