Subject RE: WARNING: Connection not closed by caller - messages produced byOpenJPA?
Date Thu, 29 Mar 2007 08:46:19 GMT
So my feeling is that we need to get to the bottom of the "WARNING:
Connection not closed by caller" line. Do you have any idea what part of
your framework is issuing that statement, and under what situations it
can happen? Can you get a stack from when it is issued?

Similarly, do you know more details about where this is failing? The
exception seems to be happening because of concurrent access to entity
beans (i.e., not JPA entities). Are you using BMP entity beans backed by
JPA entities or something like that? Is it possible to get a stack from
where this message is logged, or at least more details about what the
biz method in question is?

(None of the messages you've posted look like anything that OpenJPA
would ever generate.)
