Cancelling registration on single MultiTenantAwareComponent cancels registrations on all and closes AxonServer connection

[oleborne]

Basic information

• Axon Framework version: 4.9.2
• JDK version: 17
• Multi-Tenancy Extension version: 4.9.2
• Complete executable reproducer if available (e.g. GitHub Repo): -

Steps to reproduce

1. start a app using the Multi-Tenancy Extension connected to a AxonServer
2. register MultiTenantAwareComponent against the TenantProvider (auto-configured to AxonServerTenantProvider)
3. cancel that registration

Expected behaviour

All the individual tenant registration from the concerned MultiTenantAwareComponent are cancelled.
No other side-effects:

• registrations for other MultiTenantAwareComponent are maintained
• connection to Axon Server is maintained for all tenants

Actual behaviour

Registration for all MultiTenantAwareComponent are cancelled on all tenants, not just the concerned MultiTenantAwareComponent.
Connection for all tenants are closed on Axon Server.

Thanks for reporting this issue, based in a quick inspection, it appears this is indeed a bug.
We are already working on a patch that should be released in few weeks so we will include a fix for this issue as well.

I would like to propose a workaround if this is blocking you at the moment, but need more information on use case.
Are you building your own tenant aware component or you want to deregister a existing one?

You may also reach me to stefan.dragisic@axoniq.io if you want to share this information privately.

It is not blocking me: I was reading the code while implementing my own multi-tenant provider and I spotted the issue.
