Brian Viveiros commented on HHH-1305:
-------------------------------------
I'm seeing this when a JBPM timer triggers an Action. The Action creates a new
hibernate session and does some database work then comits.
The following line in org.jbpm.scheduler.impl.SchedulerThread.executeTimers() results in
the exception:
// save the process instance
jbpmContext.save(timer.getProcessInstance());
Is there a workaround to suppress this message? I can set logging to something higer than
INFO but then I might miss out on other messages.
Thanks.
Better exception message for version type mismatch
--------------------------------------------------
Key: HHH-1305
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1305
Project: Hibernate3
Type: Improvement
Components: core
Versions: 3.1 rc3
Reporter: Tom Baeyens
Priority: Minor
Documentation says correctly that the default type of a version is integer. When you
don't specify the type and use a long member field, hibernate doesn't use
reflection to determine the type of the version member field and generates an exception
that doesn't really relate to the problem:
