HHH000260: Exception calling user Synchronization - hibernate update indexes

HHH000260: Exception calling user Synchronization [org.hibernate.search.backend.impl.EventSourceTransactionContext$BeforeCommitSynchronizationDelegator@b4884752] : org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.myapp.loan.LoanApplication.subloans, could not initialize proxy - the owning Session was closed>

Caused by: org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.myapp.entities.LoanApplication.subloans, could not initialize proxy - the owning Session was closed

Below is the code line causing this issue.

org.hibernate.search.jpa.FullTextEntityManager fullTextEntityManager = org.hibernate.search.jpa.Search
.getFullTextEntityManager(entityManager);

fullTextEntityManager.index(loanApplication);

Session is marked as closed which doesn't allow the entity to update the indexes. Please see the attached testcase.

Update AbstractLazyInitializer.java to fix below issue for setting index from search in version hibernate-core 5.2.8

// Old Code

if ( session.isClosed() ) {
throw new SessionException(
"Session is closed. The read-only/modifiable setting is only accessible when the proxy is associated with an open session."
);
}

// Updated Code

if ( !session.isOpenOrWaitingForAutoClose() ) {
throw new SessionException(
"Session is closed. The read-only/modifiable setting is only accessible when the proxy is associated with an open session."
);
}
