Data loss after update to Quarkus 1.10.5

[bobbyphilip]

I was running on Quarkus 1.9.1. I recently updated directly to 1.10.5
I started seeing some db entries get wiped out, when accessing a related table.
I have been able to reproduce it in my environment with a simple db read now.
I use postgres, panache, hibernatesearch among other extensions.

It basically boils down to something like

@Entity
@RegisterForReflection
@Table(name = "books")
@Indexed
public class Book extends PanacheEntityBase implements Serializable {
//various fields...
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(updatable = false, name = "shop_id")
@JsonbTransient
private Shop shop;
}

What happens is when I call Book.findById(), the data in the corresponding Shop entity gets set to null.
I am not sure if there is something wrong, in the way I have written the entity, but this used to work in 1.9

I then took Quarkus v1.10.3
I now get an exception in the same sequence.

14:01:19.625 WARN [co.ar.at.arjuna] beforeCompletion ARJUNA012125: TwoPhaseCoordinator.beforeCompletion - failed for SynchronizationImple< 0:ffffc0a80e70:adb1:5ff8578d:8, org.hibernate.resource.transaction.backend.jta.internal.synchronization.RegisteredSynchronization@147062e3 >: java.lang.NullPointerException

at java.base/java.util.BitSet$1BitSetSpliterator.forEachRemaining(BitSet.java:1283)

Since the transaction fails, I dont have data loss, but looks like something is trying to overwrite the shop entity
Commenting out the Shop entity from Book, causes everything to work ok, in both versions
I have tracked down the change in behaviour to the CRM changes in 1.10.4

I have been able to reproduce this reliably in my environment, but havent been able to create a standalone example.

@Sanne Any clues on why this could happen?

I experience the same issue. It occurs if a method that performs the select is @Transactional and does not load the full entity tree -i.e. some lazy association is not loaded. Then the hibernate will trigger an updateAction in the doFlush handler, and will try to make an update on the not-loaded entity, setting all its fields to null except id. The same behaviour is in 1.11.1 but I too have not yet been able to reproduce it in a simple new project(the project where it happens every time is a fairly complex). Will report back when I managed to prepare a reproduction case.

Sorry I missed this, too much going on. I'll need to ask my teammates for help.

@dreab8 / @beikov could one of you please have a look? Looks like an NPE on the new BitSets code.

I managed to create a repro case https://github.com/yntelectual/quarkus-bug-14201 along with a small readme, but it is really weird: there are several ways how to avoid the bug behaviour e.g. removal of a lazy association, removal of attribute in parent class 😱.. so it feel pretty strange. Looking forward to any result.

Thanks @yntelectual for the reproducer, I'm going to give a look at it.

[bobbyphilip]

@yntelectual Thanks for confirming this issue. I thought I was going crazy.

Opened a Jira https://hibernate.atlassian.net/browse/HHH-14424, working on it.
