This is related to the changes introduced as part of ISPN-1233. In Hot Rod servers, cluster ID generator initialization can fail to assign an initial view rank if the default cache is not clustered but other caches are. A better solution would be to simply cache the cache manager on construction, and if a new version for a clustered cache is created and the rank is not set yet (i.e. in cases such as AS7 where cache manager is started before the servers themselves), use the cached cache manager's transport to quickly calculate the view rank.

This won't happen with Memcached because you can only interact with the default cache.
