----------------------------------------------------------------
I think this also happens even if connect is called via the process() method.
AFAICT, from reading the code, it is due to ZkStateReader being instantiated
once in the connect string, but not really being notified if/when
cores/collections are available b/c it doesn't have anything it can set watches
on, yet, b/c Solr may not be up yet.
I will try to write up a test to see if I can reproduce this.
