How to stop camel route intermediately while processing ?

Issue

• While using camel routes to process the messages, An issue is observed with stopping the route and the following are the details:

• Configuration of the route is as following:

from("jms:queue:queue1 ? concurrentConsumers = 5 & maxConcurrentConsumers = 25 & maxMessagesPerTask=25") 
                        .transacted() 
                        .process(new Processmyprocess()) 
                       .to("jms:queue:queue2"); 

• There are thousands of messages in side the queue1 to be processed, the route is processing the messages from "queue1" in between Is it possible to stop the route.

• Tried configuring the "ShutdownStrategy" as following

camelContext.getShutdownStrategy().setTimeout(2);

• For stopping the route following API is being used:

camelContext.stopRoute(routeId);

• Still unable to stop the route with in 2 seconds. For stopping of the route it is taking 300 seconds (Default Configuration).
