Spring Boot 3.5's dependency management should have been upgraded to MongoDB 5.5.0

[vanta]

After migration to SB 3.5.0 I can see in my project (snippet from Gradle's dep task):

|    \--- org.springframework.boot:spring-boot-starter-data-mongodb -> 3.5.0
|         +--- org.springframework.boot:spring-boot-starter:3.5.0 (*)
|         +--- org.mongodb:mongodb-driver-sync:5.4.0
|         |    +--- org.mongodb:bson:5.4.0 -> 5.5.0
|         |    \--- org.mongodb:mongodb-driver-core:5.4.0 -> 5.5.0
|         |         \--- org.mongodb:bson:5.5.0
|         \--- org.springframework.data:spring-data-mongodb:4.5.0
|              +--- org.mongodb:mongodb-driver-core:5.5.0 (*)

You can see two version of mongodb-driver-core: 5.4.0 and 5.5.0 that are both brought by spring-boot-starter-data-mongodb, one directly and the other one transitively (via org.springframework.data:spring-data-mongodb). The snippet from the application log (from running test) is as below:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

Thanks for reporting the issue. It looks like an upgrade happened in Spring Data a couple of weeks ago and we had already moved to track only patch releases at that point.

I think we should consider breaking our own rules and upgrading to 5.5.0 in Spring Boot 3.5.1. Flagging to see what the team thing.

[wilkinsona]

Yeah, I think we should upgrade. However, that doesn't explain the mismatched versions.

@vanta, if you're using Spring Boot's dependency management, you should see 5.4.0 for all Mongo driver dependencies. For example, here's the compile classpath of a freshly generated project from start.spring.io:

compileClasspath - Compile classpath for source set 'main'.

We faced the same issue for MongoDB driver dependencies in 3.5.0. It does not happen if io.spring.dependency-management is used - all versions of org.mongodb: dependencies are forced to 5.4.0 in that case. It can be reproduced if Gradle platform is used instead.

The simplest reproducer uses a new start.spring.io project with a patch:

That explains it. Thank you, @GreyTeardrop. You could avoid that by using enforcedPlatform.
