2.8.6 NoSuchMethodException with Hibernate 5.2 #102
Description
Missing method:
org.hibernate.resource.transaction.spi.TransactionCoordinator.isJta()
Here's a patch to fix it that is guaranteed to be future-compatible because it asks through JPA, not the Hibernate-only APIs.

You can actually remove everything else from the SessionReader static class.
Here's the Javadoc comment from the JPA specifications.
/**
* Return the resource-level <code>EntityTransaction</code> object.
* The <code>EntityTransaction</code> instance may be used serially to
* begin and commit multiple transactions.
* @return EntityTransaction instance
* @throws IllegalStateException if invoked on a JTA
* entity manager

public EntityTransaction getTransaction();
