      1: run code
      import com.mongodb.BasicDBObject;
      import com.mongodb.Mongo;
      import com.mongodb.MongoException.DuplicateKey;
      import com.mongodb.WriteConcern;
      import org.junit.Test;
      import org.slf4j.Logger;
      import org.slf4j.LoggerFactory;

      import java.net.UnknownHostException;

      /**

        public class BDBOSerializeUtilsTest {
        private static final Logger log = LoggerFactory.getLogger(
        BDBOSerializeUtilsTest.class);

      @Test
      public void testSerialize() throws UnknownHostException {
      final BasicDBObject object = new BasicDBObject("_id",
      new byte[]

      {1, 2, 3}

      );
      Mongo mongo = new Mongo();
      mongo.setWriteConcern(WriteConcern.ACKNOWLEDGED);
      mongo.getDB("testSerialize").getCollection("test").insert(object);
      mongo.getDB("testSerialize").getCollection("test").insert(object);
      }
      }
      2. Look at the exception message

Look at the exception message

      Description

      This code throws MongoException.DuplicateKey, as expected. But error message doesn't contain actual key:
      com.mongodb.MongoException$DuplicateKey: E11000 duplicate key error index: testSerialize.test.$id dup key: { : BinData }

      Looks like this "{ : BinData}" comes from the server side. Is it any way to see actual key, that is duplicated? Just BinData is not user-friendly message at all.
