ActiveMQ and ThreadPoolExecutor working together

Question

I need to fetch the data from activeMQ and then pass it to executors running in ThreadPoolExecutor.

The problem is, I don't have to fetch next data from queue, until I have at least one thread in the pool sitting idle, ready to take on this task.

I can just busy wait until activeCount< poolSize. But I would appreciate any solution with some asynchronous handling of this. Thanks in advance.

You can try this

final ThreadPoolExecutor executor=...
new Thread(new Runnable(){
public void run(){
    while(true){
        if(executor.getActiveCount()<executor.getCorePoolSize())
            executor.execute(mq.get());
      }
}).start();
