Dmitry Karachentsev created IGNITE-4487:
-------------------------------------------

             Summary: NPE on query execution
                 Key: IGNITE-4487
                 URL: https://issues.apache.org/jira/browse/IGNITE-4487
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 1.8
            Reporter: Dmitry Karachentsev
             Fix For: 2.0


NPE may be thrown when called destroyCache() and started querying.

Attached example reproduces this case when GridDiscoveryManager#removeCacheFilter called but cache state haven't been changed to STOPPED org.apache.ignite.internal.processors.cache.GridCacheGateway#onStopped.
