question: public void reserveConnections ( long startTime , long ackTimeout , long ackSDTimeout ) { for ( Iterator it = cons . iterator ( ) ; it . hasNext ( ) ; ) { Connection con = ( Connection ) it . next ( ) ; con . setInUse ( true , startTime , ackTimeout , ackSDTimeout , cons ) ; if ( ackTimeout > 0 ) { con . scheduleAckTimeouts ( ) ; } } }
target:  set connections to be "in use" and schedule alert tasks
