> CDC doesn't work If some cache objects transformation is applied (see the [https://cwiki.apache.org/confluence/display/IGNITE/IEP-97+Cache+objects+transformation|https://cwiki.apache.org/confluence/display/IGNITE/IEP-97+Cache+objects+transformation]).
> ignite_cdc.sh utility produces the NPE (see below). The immediate reason of the NPE is that ignite_cdc.sh uses the reduced version of the context (StandaloneGridKernalContext), which doesn't contain the GridCacheProcessor.
