Commons VFS stack trace when running Mongobee in JAR
See original GitHub issueOverview of the issue
This doesn’t seem to stop the application from working, but it does look like something is wrong. There’s a stack trace on startup when using MonboDB.

Just in case someone finds this ticket when googling, the stack trace still happens in JHipster 4.3.0:
So the issue is that there is no MongoBee migration on a brand new microservice, as it doesn’t have any user management code. Of course, as soon as you add some entities, this folder will have migrations in it, so that’s only very temporary. I’m doing a PR to remove the warnings.
