How to disable mongodb java driver's DefaultServerMonitor Thread

I added apache metamodel into my project.

<dependency>
    <groupId>org.apache.metamodel</groupId>
    <artifactId>MetaModel-full</artifactId>
    <version>5.0.0</version>
</dependency>

mongo-java-driver came as a dependency.

[INFO] |  +- org.apache.metamodel:MetaModel-mongodb-mongo3:jar:5.0.0:compile
[INFO] |  |  +- org.apache.metamodel:MetaModel-mongodb-common:jar:5.0.0:compile
[INFO] |  |  \- org.mongodb:mongo-java-driver:jar:3.4.3:compile
[INFO] |  +- org.apache.metamodel:MetaModel-mongodb-mongo2:jar:5.0.0:compile

Then I see some logs like.

2018-01-16 02:33:09.467  INFO 15417 --- [  restartedMain] org.mongodb.driver.cluster               : Cluster created with settings {hosts=[localhost:27017], mode=SINGLE, requiredClusterType=UNKNOWN, serverSelectionTimeout='30000 ms', maxWaitQueueSize=500}

When I dig source code of mongo-java-driver I see mongo-java-driver starts a Thread to monitor default mongodb server. I dont want to exclude mongodb driver but how can I disable com.mongodb.connection.DefaultServerMonitor thread.

After further search I realized that it is spring-boot autoconfiguration issue. My application is a spring-boot app. spring-boot auto config finds a mongos-java-driver jar in classpath and start-up mongo-drive.

Added @EnableAutoConfiguration(exclude = {MongoAutoConfiguration.class}) and mongo-java-driver doesn't start anymore.
