singleton creation (ot)

[Felipe Schnack]

  I was wondering... this code is valid to avoid excessive use of
synchronized code? I think so, but we never know :-)
  This is the default getInstance() method of a singleton (simplified):

public Object getInstance()
{
  if (INSTANCE == null)
  {
    synchronized (this)
    {
      if (INSTANCE == null)
      {
        INSTANCE = this.getClass().newInstance();
      }
    }
  }
  return INSTANCE;
}
