Spring Boot 2.0.0.M2 doesn't work with Spring Data MongoDB Kay.M4

When I use the attached testcase I cannot start the server implemented in Main.java (see the console output below).

I’m using the following versions: JDK 8u131 Gradle 4.1-milestone-1 MongoDB 3.5.10

The local MongoDB server is started w/o an authentication database. I get the same error when using an authentication database.

Console output:

Starting a Gradle Daemon, 1 busy and 2 incompatible Daemons could not be reused, use --status for details

@snicoll I wonder if the scanner could output a warning to that effect at compile time when the resulting index is below a certain size threshold?

@snicoll a few weeks ago I read about the indexer (in the JIRA ticket system?) and made a note that we should add a dependency on the indexer when we start piloting the upgrade. Sorry, my failure.
