According to the PR debezium/debezium#114, in case of the "zero-value" timestamp column type, the Java date will convert to epoch time as 1970-01-01, but the datetime column type (not null) - the connector will throw an exception like bellow.

The connector knows the datetime column is mandatory, but the debezium connector always convert "zero-value" as nulled value, then the connect schema validate again and it will throw an exception.
