How can I make JNDI Registry thread safe?

Question

I have a class which creates the camel routes dynamically. Previously it creates routes through a simple loop, But now I want to make sure all routes are start at the same time. For that I used FutureTask. Now I got the exception,

java.lang.UnsupportedOperationException: JBAS011859: Naming context is read-only

There is a JNDI registry used in CreateCamelRoute class. whenever trying to bind object to that, it throws the exception. How can I make JNDI Registry thread safe?

public StartRoutes(){
           List<DestinationTransport> transport = findAll();

            FutureTask[] randomNumberTasks = new FutureTask[transport.size()];

            for (int i = 0; i < transport.size(); i++) {
                Callable callable = new CallableExampleDT(transport.get(i));

                randomNumberTasks[i] = new FutureTask(callable);

                Thread t = new Thread(randomNumberTasks[i]);
                t.start();
            }

            for (int i = 0; i < transport.size(); i++) {
                System.out.println(randomNumberTasks[i].get());
                messages.add((String) randomNumberTasks[i].get());
            }
        }
}

CallableExampleDT

public class CallableExampleDT implements Callable<Object> {
    private final Object transport;

    public CallableExampleDT(Object transport) {
       this.transport = transport;
    }

public synchronized Object call() throws Exception {

    String status = "";
    DestinationTransport t= (DestinationTransport) transport;
    try {
            route.createRoute(t);
    } catch (Exception e) {
        e.printStackTrace();
    }

    Thread.sleep(5000);


    if (route.checkRoute(t.id()))
        status= LoggingMessage.STARTED;
    else
        status= LoggingMessage.IS_STOPPED;

    return status;
}

AsyncCamelDynamicFTPRoute

public class AsyncCamelDynamicFTPRoute{

    DefaultCamelContext defaultCamelContext = null;

    private CamelContext context = null;

    JndiRegistry jndi = new JndiRegistry();

    public synchronized void createRoute(Object object) throws ApplicationException {
        DestinationTransport dt= (DestinationTransport) object;
        String destinationTransport= dt.id();


        if(Objects.isNull(jndi.lookupByName("DYNAMIC_QUEUES_"+dt.getDestinationTransport()))){
            defaultCamelContext = new DefaultCamelContext();
            defaultCamelContext.setName("DYNAMIC_QUEUES_"+dt.getDestinationTransport());

            //getting exception here, while trying to bind
            jndi.bind("DYNAMIC_QUEUES_"+dt.getDestinationTransport(), defaultCamelContext);

        }
        else {

                defaultCamelContext = (DefaultCamelContext) jndi.lookup("DYNAMIC_QUEUES_"+dt.getDestinationTransport());

        }
        context= defaultCamelContext;

        context.getProperties().put(Exchange.LOG_DEBUG_BODY_STREAMS, "true");

            context.addRoutes(new RouteBuilder() {
                    /**Code for creating route**/
           }

      context.start();

 }
