PlacementService disposal?

[alexander-jesner-AP]

During shutdown of my application I get log output regarding an ObjectDisposedException:

System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'IServiceProvider'.
   at Microsoft.Extensions.DependencyInjection.ServiceLookup.ThrowHelper.ThrowObjectDisposedException()
   at Microsoft.Extensions.DependencyInjection.ServiceLookup.ServiceProviderEngineScope.GetRequiredKeyedService(Type serviceType, Object serviceKey)
   at Orleans.Runtime.Placement.PlacementService.PlacementWorker.GetOrPlaceActivationAsync(Message firstMessage) in /_/src/Orleans.Runtime/Placement/PlacementService.cs:line 380
   at Orleans.Runtime.Placement.PlacementService.PlacementWorker.AddressWaitingMessages(GrainPlacementWorkItem completedWorkItem) in /_/src/Orleans.Runtime/Placement/PlacementService.cs:line 339

The exception is not bubbling out, it is caught in the PlacementService and logged.

I was asking myself if the PlacementService should actually be disposable and the while(true) in

orleans/src/Orleans.Runtime/Placement/PlacementService.cs

Line 282 in 86db32b

while (true)

should in fact be a while(undisposed).

Using Orleans 9.2.1.

Thanks for your help!
