org.apache.camel.util.concurrent.SizedScheduledExecutorService
A sized {@link ScheduledExecutorService} which will reject executing tasks if the task queue is full.
The {@link ScheduledThreadPoolExecutor} which is the default implementation of the {@link ScheduledExecutorService}has unbounded task queue, which mean you can keep scheduling tasks which may cause the system to run out of memory.
This class is a wrapped for {@link ScheduledThreadPoolExecutor} to reject executing tasks if an upper limitof the task queue has been reached.


        // need to wrap the thread pool in a sized to guard against the problem that the
        // JDK created thread pool has an unbounded queue (see class javadoc), which mean
        // we could potentially keep adding tasks, and run out of memory.
        if (profile.getMaxPoolSize() > 0) {
            return new SizedScheduledExecutorService(answer, profile.getMaxQueueSize());
        } else {
            return answer;
        }
