[hibernate-dev] Multitenancy Per Schema Fails With NPE

[Steve Ebersole]

1) This is a list for discussing the development of Hibernate itself, not
for discussing usage of Hibernate.  Please use the forums, StackOverflow,
or #hibernate IRC for user questions.

2) If this really leads to a NPE in *Hibernate* (not your code) trying to
open a connection, then that would be a bug.  If that is the case, please
open a Jira, and be sure to include (a) a test case and (b) the full stack
trace for the NPE.
