Eric Norman commented on SLING-10402:
-------------------------------------
FYI: I tried the now released oak 1.40.0 with mongo-java-driver:3.12.8 and it
seems to work correctly again, so it looks like the fix for OAK-9357 does
resolve the problem.
I created SLING-10459 to track updating the starter to 1.40.0
> MongoDB doesn't work anymore with Sling Starter

> 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.
