DCP Exception when performing operation

While using DCP through java sdk, during running of dcp check, if I try performing any document operations, it’s throwing exception. But, when I initially perform operations, then starts dcp streaming, then it’s working fine. Please explain.

Note that DCP is not directly supported at the moment. It is Open Source, of course, but it’s not currently a public interface.

I can’t really answer your question without more information. What do you mean by running “dcp check”. What kind of exception?

We can probably help more if you describe the system, the scenario, the observed behavior and what you expect.
