Example 6 with State

use of com.google.common.util.concurrent.Service.State in project guava by google.

the class AbstractServiceTest method testListenerDoesntDeadlockOnStopAndWaitFromTerminated.

public void testListenerDoesntDeadlockOnStopAndWaitFromTerminated() throws Exception {
    final NoOpThreadedService service = new NoOpThreadedService();
    service.addListener(new Listener() {

        @Override
        public void terminated(State from) {
            service.stopAsync().awaitTerminated();
        }
    }, directExecutor());
    service.startAsync().awaitRunning();
    Thread thread = new Thread() {

        @Override
        public void run() {
