Alexandr Kuramshin commented on IGNITE-5889:
--------------------------------------------
[~v.pyatkov],
Actually you won't get an error upon {{getOrCreateCaches}} invocation with two
identical cache configurations (as in your test).
Because {{getOrCreateCaches}} internally calls {{dynamicStartCaches}} with
{{failIfExists == false}}.
But where is two bugs:
1. Starting unnecessary client cache inside {{prepareCacheChangeRequest}} after
checking that {{desc != null && failIfExists == false && nearCfg == null}}.
2. Calling {{clientCachesToStart}} before the server cache was actually started.
The second bug was fixed in https://issues.apache.org/jira/browse/IGNITE-5763
The first may be fixed in this ticket context.
> Exception message confused when double cache configuration by some mistake.
