Description

We have an enterprise application, and we are using embedded ActiveMQ.
We are currently using 5.15.2 version. We tried the latest(5.15.9) version, but the issue still persists.

ActiveMQ Connector Executor threads are being created in ActiveMQConnection class.

 

ActiveMQ Connection Executor threads are not going away even after restarting the broker programmatically. Threads keep increasing and after bouncing the Broker, they don't go away.

 

Steps to reproduce:
1. Run load test on ActiveMQ.
2. Take thread dumps
3. Stop the Broker multiple times
4. Take thread dumps again.

Result: Compare the thread dumps, executor threads from the previous dump will be present in all next dumps.
