Cache has been closed exception

I am getting "Cache has been closed" exception when accessing Ignite Cache for querying. What I'm doing is simply,

CacheConfiguration cfg = new CacheConfiguration();
cacheConfiguration.setCacheMode(CacheMode.REPLICATED);
cacheConfiguration.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL_SNAPSHOT);        cacheConfiguration.setWriteSynchronizationMode(CacheWriteSynchronizationMode.PRIMARY_SYNC);
IgniteCache cache = ignite.getOrCreateCache(cfg);

After initializing this, in other place in my code I am calling cache.get("key"); But it's throwing exception.

Cache variable is member of some class's object. Why can't the cache be kept open till it is closed manually.

I AM NOT CLOSING IT ANYWHERE

Usually it happens when client is disconnected, servers go down, or client rejoins with new ID since you're not calling .close() or .destory() anywhere in your code.
