Hi Maris,
We are trying to use sequoia with firebird 2.0.3. I have one
controller with 3 database backends and and it fails with NPE.
Everything works if I use only one backend (any of them).
Wow, this one for sure is unusual. This is likely to be due to some
non-compliancy in your driver implementation.
Anyway, you need to file a new JIRA entry for this bug.
Are you using the same database version for each database backend?
Are you using the exact same database driver for each backend?
I will prepare a patch for this one, this is an easy fix.
Thanks for your feedback,
Emmanuel
