Description

This issue is hard to reproduce, but it's possible that ServiceTopologyCallable will be executed on a new node prior to initialization of utility cache. In this case cache will be null and serviceTopology method with throw an NPE. We should call GridCacheProcessor.awaitStarted() prior to using the cache.
