      Description

      mongodb-driver-sync” (v3.8.2)

      A `MongoCommandException` is thrown in `replaceOne` when a write concern cannot be fulfilled. But the Javadocs say it should be a `MongoWriteConcernException ` 

      An example stacktrace:

      com.mongodb.MongoCommandException: Command failed with error 64 (WriteConcernFailed): 'waiting for replication timed out; Error details: { wtimeout: true }' on server <HOST>:<p>. The full response is { "ok" : 0.0, "errmsg" : "waiting for replication timed out; Error details: { wtimeout: true }", "code" : 64, "codeName" : "WriteConcernFailed", "operationTime" : { "$timestamp" : { "t" : 1555309144, "i" : 1 } }, "$clusterTime" : { "clusterTime" : { "$timestamp" : { "t" : 1555309144, "i" : 1 } }, "signature" : { "hash" : { "$binary" : "0oD+9Fb/yWy62TNt56fQ821auf8=", "$type" : "00" }, "keyId" : { "$numberLong" : "6634436738045444126" } } } }

      There seem to be at least two solutions:

      1. Update the Javadocs
      2. Catch this MongoCommandException and wrap in MongoWriteConcernException
