> Previously, ComputeCache used a stringified Key to ensure we don't create another ComputeService for the same provider.  At some point, Key was modified to use both a string and a commons configuration object.  Since commons configuration doesn't implement hashCode in a predictable way, the ComputeCache creates a new ComputeServiceContext each time it is used.  Since we don't log or test this, it was easy to miss.
