In a JMS Proxy service for a topic, durable subscription of JMS Topic is removed for a while when making changes to the JMS Topic proxy service causes message loss.
1. Create a JMS based proxy service for a topic with durable subscription enabled.
2. Deploy the proxy (Activate the changes)
3. Keep sending message to the topic and the proxy created on step 1 consumes the message
4. Go ahead and update the JMS based proxy service (for eg. change the retry count of the JMS Proxy service to some value.
5. Activate the changes.
During the above process some of the messages are getting dropped for a while because of durable subscription is removed and recreated for the modified JMS Proxy service.
