ActiveMQ "Scheduler" Daemon Threads not terminating

I'm using ActiveMQ 5.5 with an embedded broker. All messages are non persistent. Producer and Consumer both run within same JVM. Advisory Support is disabled.

Everything is working fine. My question is about these "Scheduler" threads running as daemon threads and why they are not terminated.

I ran a test where I created about 10 consumers (no producers started) and closed them. I've confirmed that my consumers close successfully, by us开发者_运维技巧ing advisory support etc...

So inspite of the consumers closing successfully, I see that there's a scheduler Daemon thread created for each consumer, and its not terminated, even if I wait for a long time.

Why is that so? Is there anything I'm not doing?

Here's how my stack stack looked like in Eclipse...there's 10 daemon scheduler threads, each created for a consumer.
