Hi Gail, Yes, WFLY-11243 [1] is caching TransactionSynchronizationRegistry at the WildFly level, which is great for WildFly applications but other platforms might benefit from one of the following:
A. Reducing the number of Hibernate ORM calls to JndiService#locate (the TransactionSynchronizationRegistry). In a WildFly 15 container managed persistence context/EntityManager, I saw that every call to EntityManager.find() in a new JTA transaction, required a call to JndiService#locate (from pulse()). This will be worked around in WildFly 16, via [1], to avoid the call to JndiService#locate. B. Or could/should we cache the TransactionSynchronizationRegistry in the SessionFactory? Which is my open question still. Apologies for the bad [2] link, I'm not sure why that is now invalid, next time I will use a gist link.
