>          Issue Type: Bug
>          Components: cache
>    Affects Versions: sprint-1

> Test scenario:
> 1) Start 2 nodes with ATOMIC cache and no backups.
> 2) Start continuous query with filter which throws an exception (say, CacheEntryListenerException as per contract).
> 3) Put near key into cache.
> 4) Observe that you got stuck.
> Root cause: CacheContinuousQuerHandler invokes filter in register()/onEntryUpdate() method. Exception is thrown form here to GridDhtAtomicCache.
> Atomic cache "updateSingle()" method, in turn, catches only IgniteCheckedException. As a result, filter exception is propagated to IO manager and simply ignored there. Aa a final result, update response is never sent to remote node.
