HI:

      When "sink.semantic = exactual-only", the following exception is thrown when recovering from svaepoint

       public static final String KAFKA_TABLE_FORMAT =

            "CREATE TABLE "+TABLE_NAME+" (\n" +

                    "  "+COLUMN_NAME+" STRING\n" +

                    ") WITH (\n" +

                    "   'connector' = 'kafka',\n" +
