December 28, 2017

This is a minor release that includes one new feature and two bug fixes.

New Features

SNI Support - The connector now supports SNI for TLS connections, provided that the user updates to Java version 1.8 update 131 or greater.

Fixed Issues

  • BsonInvalidOperationException on upsert operations - Under certain scenarios, the connector threw org.bson.BsonInvalidOperationException: Value expected to be of type OBJECT_ID is of unexpected type STRING when upserting documents, if the _id was not of type ObjectId. This now works as expected.

  • InvalidLicenseException when config is in a domain - Mule apps calling the Mongo connector that had its config in a domain would randomly throw InvalidLicenseException. This was fixed.

Known Issues

When connecting to a MongoDB instance that requires SNI, the Test Connectivity functionality in Studio may not work. The connector will still work despite this.

Fixed Issues

Fixed an issue where non-fully-qualified DNS names in Hosts field did not let you connect to MongoDB.
