Because you have explicitely called for it. Passing 'true' tells the dispose to wait for all the sessions to complete : "Releases any resources allocated by this service. Please note that this method might block as long as there are any sessions managed by this service. Warning : calling this method from a IoFutureListener with awaitTermination = true will probably lead to a deadlock." Pass 'false'.
