Hi,
If tenant domain is not set, we can derive it via tenant id, right? But the
method getCacheManager in CacheManagerFactoryImpl [1] do not do this, and
therefore fails with a NPE. Following error was observed when a datasource
addition triggered a cluster notification, and the worker node tried to
process it. Only the tenant id is set in the cluster message.
