    Description

      When creating a cluster with no explicit clustered-locks configuration, i.e. num_Owners is not defined, a `ClassCastException` is thrown if a zero-capacity node joins the cluster and attempts to use a lock:

      Previously zero-capacity node was not supported with replicated-caches, however this is no longer the case so it should be possible for clustered-locks to work with a replicated cache without defining num_owners.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
