Session receiver stops processing next sessions

[petrformanek]

Actual Behavior

1. I have simple session enabled subscription consumed by following code snippet
2. Processing of messages takes longer than MaxAutoRenewDuration
3. After processing of the first message the pump gets stuck and no other messages are processed

Expected Behavior

1. Message processing will continue with another session

Discovered bug

1. From debugging it looks like a bug in method SessionReceivePump.MessagePumpTaskAsync in finally block.
2. When calling CancelAndDisposeCancellationTokenSource(renewLockCancellationTokenSource); there is a ObjectDisposedException and because of that this.maxConcurrentSessionsSemaphoreSlim.Release(); is not called and pump gets stuck while waiting on semaphore release.

Versions

• OS platform and version: Windows 10

Might be related to issue #595.
