Roman Guseinov commented on IGNITE-9878:
----------------------------------------
[~vkulichenko], thanks for your comment.
I believe it should work like `IgniteCache<K, V>
getOrCreateCache(CacheConfiguration<K, V> cacheCfg)`. You can call this method
with the same cacheCfg multiple times without any errors.
If you try to do the same with `IgniteCache<K, V>
getOrCreateCache(CacheConfiguration<K, V> cacheCfg, NearCacheConfiguration<K,
V> nearCfg)` the first call will be successful, but the second one will fail.
Does it look correct to you? Why Ignite should throw an exception instead of
returning the same results (like for the first call)?
