[QUERY] Service Bus Processor Graceful Shutdown

[rileymichael]

Query/Question What is the intended way to drain a service bus processor in order to shutdown gracefully? We've attempted to call ServiceBusProcessorClient#stop -> wait a period of time -> call ServiceBusProcessorClient#close to allow for (most) in-flight messages to finish processing but it looks like the underlying receiver is disposed (even though the javadoc indicates the receiving links remain open?).

Here's the exception when a processor attempts to update the status after stop is called:

java.lang.IllegalStateException: Cannot perform operation 'abandoned' on a disposed receiver.
	at com.azure.messaging.servicebus.ServiceBusReceiverAsyncClient.updateDisposition(ServiceBusReceiverAsyncClient.java:1528)
	at com.azure.messaging.servicebus.ServiceBusReceiverAsyncClient.abandon(ServiceBusReceiverAsyncClient.java:509)
	at com.azure.messaging.servicebus.ServiceBusReceivedMessageContext.abandon(ServiceBusReceivedMessageContext.java:79)

If anyone in the Azure team can point out y'all's take on this, I would gladly put in some time to make a pull request to resolve the issue. However, I don't want to risk the PR getting ignored and my time thereby being wasted - see the original issue where the Azure team provided no information and closed out the work as not planned.

This is a serious problem that prevents Service Bus from being treated as a mature solution in Java workspaces.
