Description
I'm getting NPE in these tests:
https://github.com/mlinhard/infinispan/commit/d1efd673ba6c34a4f6383b167408c3ff4c3a0503
it's caused by a thread asking the cache store to load all keys after it's been shutdown.
It might be considered also a problem of LevelDB implementation that doesn't guard against this.
these are the stacktraces of the causing events:
