Possible solution can be using a method like this:

----------------------------------------------------------------
// Must be called with this instance's lock held (i.e. synchronized on this)
private void waitStateUninterruptibly(int state, boolean value)
{
  boolean interrupted = Thread.interrupted();

  while ((this.state == state) != value)
    {
      try
        {
          wait();
        }
      catch (InterruptedException e)
        {
          interrupted = true;
        }
    }

  // Keep interrupt flag unaltered
  if (interrupted)
    Thread.currentThread().interrupt();
}
----------------------------------------------------------------

And replacing the current wait loops with calls to that method:

   waitStateUninterruptibly(INITIAL, false);

and

   waitStateUninterruptibly(TERMINATED, true);
