Issue Type: Improvement Affects Versions: 5.4.18 Assignee: Unassigned Components: hibernate-core Created: 17/Jul/2020 03:26 AM Environment: java 11,
hibernate 5.4.18,
JTA: narayana-jta-5.9.0,

When I use entity manager find() method with LockModeType inside JTA transaction boundaries, throw fowling exception:

_Exception in thread "main" javax.persistence.TransactionRequiredException: no transaction is in progress
at org.hibernate.internal.AbstractSharedSessionContract.checkTransactionNeededForUpdateOperation(AbstractSharedSessionContract.java:413)
at org.hibernate.internal.SessionImpl.checkTransactionNeededForUpdateOperation(SessionImpl.java:3395)
at org.hibernate.internal.SessionImpl.find(SessionImpl.java:3310)
at org.hibernate.internal.SessionImpl.find(SessionImpl.java:3292)
at ro.alsoco.tt.test.TestJPA.run(TestJPA.java:71)
at ro.alsoco.tt.test.TestJPA.main(TestJPA.java:24)
_

This doesn't happen when I use for example createQuery or if i call clear() or flush() before find().
After a few research I saw the majority of entity manipulation methods of EntityManager (SessionImpl or AbstractSharedSessionContract classes) execute on begining pulseTransactionCoordinator(). But find() mehod not.
I don't know if there are any special reason why find method not call pulseTransactionCoordinator(), witch I saw register synchronization with JTA.
For the moment I solved my problem issuing a joinTransaction() as first command after begin transaction.

Also, the problem doesn't happen if i create entity manager inside the JTA transaction. But I have strong resons to create entity manager outside the transaction.

It is possible to call pulseTransactionCoordinator() in find() method as bellow?
Maybe in next version?

_ at Override
public <T> T find(Class<T> entityClass, Object primaryKey, LockModeType lockModeType, Map<String, Object> properties) {
checkOpen();
pulseTransactionCoordinator();
.............

Thank you,
