Yeah, which is great when you can rely on impl-specific apis.
Agreed. I'm not sure of what we should do when ORM is running in
environments that cannot rely on a NarayanaJtaPltaform. Especially,
when every call into Hibernate ORM is from a different thread (e.g.
remote EJB invocations).
I think the below idea of deferring to the JtaPlatform to indicate the
"type of timeout tracking" to do, is the best approach.
I'll consider this, but its not super high on my priority list. I guess
we could implement some kind of way for the JtaPlatform to indicate the
"type of timeout tracking" to do and develop a new NarayanaJtaPltaform
that does this.
Is this more of an ORM 5.1 or 6.0 change?

I think that Hibernate ORM could do something similar with the
org.jboss.tm.listener.TransactionListenerRegistry to protect against
clearing the persistence context from a non-application thread, while
the application thread may be actively using the persistence context.
I think this approach is simpler than the thread id tracking.
