Connection pool maintenance thread never ending?

Folks:

Has anyone worked with connection pools in JT400?

I'm using the AS400ConnectionPool and JDBCConnectionPool for my
application ... so far I haven't had any problems with them, but I just
noticed something the other day.

The AS400ConnectionPoolMaintenanceThread never seems to end.  And when a
new connection pool is created, so is a new maintenance thread.

>From what I can see, the run method, in the
com.ibm.as400.access.PoolMaintenance object, does not have any ability
to exit and shutdown.

---------

  public synchronized void run()
  {
    if (Trace.traceOn_)
    {
      Trace.log(Trace.INFORMATION, "Connection pool maintenance daemon
is started...");
    }
    run_ = true;
    while (true)
    {
      if (run_)
      {
        try
        {
          // sleep for cleanup interval.
          wait(pool_.getCleanupInterval());
        }
        catch (InterruptedException ie)
        {
          Trace.log(Trace.ERROR, "Connection pool maintenance daemon
failed.");
        }
        pool_.cleanupConnections();

        lastRun_ = System.currentTimeMillis();       // set the time of
last run.
      }
      else
      {
        try
        {
          wait();
        }
        catch (InterruptedException e)
        {
          Trace.log(Trace.ERROR, "Connection pool maintenance daemon
failed.");
        }
      }
    }
  }

  /**
  *  Sets whether the maintenance thread is running.
  *  @param running true if running; false otherwise.
  **/
  public synchronized void setRunning(boolean running)
  {
    if (run_ != running)
    {
      run_ = running;
      notify();
    }
  }
---------

As you can see from the above, the entire loop is unconditional and
never breaks out.

Is this a bug, or am I just not understanding threads well enough (which
I freely admit to not being an expert in).

Thanks!
