Any problem with using two instances of Executor service one after the other?

In my code, I have two instances of of Executor Service with cached thread pools.

For example,

I have my service calling the runner object which implements runnable. I call runProcess method twice in a row. My question is if this is if one service will interfere with the other service. I need the threads in each service to finish one after the other. Please let me know.

void runProcess(){

try{
ExecutorService service = Executors.newCachedThreadPool();
TestRunner runner = new Runner(object obj);
//some code
}
finally{

service.shutdown();
service.awaittermination(1,TIMEUNIT.HOURS)

}
}

The call to Executors.newCachedThreadPool(); creates a new ExectuorService each time. So, they won't interfere with each other.
However, there is no gaurantee on which service will finish first.
