It appears that EntityTransaction .commit() does not release a pessimistic lock - test code below. I tried it in with the current (2.7.6_01) and older versions (2.6.9, 2.5.7, 2.4.7) with the same result. (side note: EntityTransaction .rollback() releases it correctly) // Account.java package icke

A complete idiom for custom application management of the EntityManager and its associated resource-local EntityTransaction is as follows: EntityManager entityManager = entityManagerFactory.createEntityManager(); EntityTransaction transaction

Jakarta Persistence (JPA) Method in jakarta.persistence.EntityManager EntityTransaction getTransaction() Return the resource-level EntityTransaction object. The EntityTransaction instance may be used serially to begin and commit multiple transactions. Returns: EntityTransaction instance. Throws
