Hibernate null transaction

[aderosso]

We're getting the error message:

com.isomorphic.hibernate.HibernateTransaction [c.i.h.HibernateTransaction(warn:78)] Attempted to commit null transaction

It also looks like when this message happens, that's keeping a connection out from our DB pool, which is exhausting the pool. Is there something we can do to fix this transaction warning message?

How do we reproduce this? If we know how this happens, then we can fix it or suggest a workaround.
