The error happens regardless of the multitenant connection provider & tenant identifier resolver settings.

I'm using multitenancy and it works, so the problem isn't with with Hibernate's basic multitenancy support, but that there are two issues:

1. TableGenerator doesn't support multitenancy
2. SchemaExport doesn't support multitenancy

but yeah, if these settings are missing/misconfigured then Hibernate should throw a better exception instead of NPE.
