Eric Norman commented on SLING-10402:
-------------------------------------
[~rombert] I suppose we could hardcode a specific version for mongo-java-driver
in the maven-version-rules.xml of org-apache-sling-build-version-rules if oak
requires a specific version of the mongo-java-driver and no other version is
expected to work, but is that really the case here?
I'm no expert on the mongo-java-driver, but can someone explain to me what the
root of the problem is here? It seems to me that the version in the oak parent
pom should be just the minimum version, so newer compatible versions of
mongo-java-driver should reasonably be expected to work in the runtime as well.
And from what I have just read on [https://docs.mongodb.com/drivers/java/] it
says that the mongo-java-driver version 3.11 to 4.2 are supposed to be
compatible with MongoDB 4.0.x and all of our supported JVM versions.

> Affects Versions: Starter 12
> Environment: Sling-Starter 12-SNAPSHOT (commit a6b94beb7b) with JDK
> 11 on MacOS

> When starting the Sling Starter 12 SNAPSHOT with, the Repository doesn't seem
> to work properly right now when I'm using MongoDB. It starts up, but when I
> open http://localhost:8080/bin/browser.html, I get an exception reading from
> the database (see below). I tried with mongodb 4.4.6 (the latest one) and
> 4.0.3. This issue seems to be connected to the version of
> org.mongodb:mongo-java-driver - it came in when it was upgraded from 3.8.2 to
> 3.12.7; if I downgrade to 3.10.2 it works, but with 3.11.3, 3.12.7 or 3.12.8
> it doesn't.
