Hi all!

I have some issue when I perform http TestNG tests through multiple threads.

public void updateFrameWithData1() {
//create unique frame
// then update it

public void updateFrameWithData2() {
//create unique frame
// then update it

and so on.. multiple tests via for example 8 threads

If I run tests in one thread all is ok! But in the above case I got 500 error response - No row with the given identifier exists

And on the server I see such error:

javax.persistence.EntityNotFoundException: No row with the given identifier exists: [com.aginity.amp.catalogservice.domain.model.workspace.asset.frame.frame.FrameLogic#48951]
    at org.hibernate.internal.ExceptionConverterImpl.convert(ExceptionConverterImpl.java:111)
    at org.hibernate.internal.ExceptionConverterImpl.convert(ExceptionConverterImpl.java:155)
    at org.hibernate.query.internal.AbstractProducedQuery.list(AbstractProducedQuery.java:1419)

I have
hibernate.current_session_context_class: thread
for current session.
Hibernate version is 5.2.8

The structure of my classes:

public class Frame  {

@OneToOne(cascade = {CascadeType.ALL}, orphanRemoval = true, fetch = FetchType.EAGER)
@JoinColumn(name = "frame_logic_key", referencedColumnName = "frame_logic_key")
private FrameLogic logic;

//other fields

@AttributeOverride(name = "id", column = @Column(name = "view_frame_logic_key"))
public class FrameLogic extends IdentifiedDomainObject {
// fields of class


So the relationship is unidirectional via "frame_logic_key" column in corresponding tables of Frame and FrameLogic.

The EntityNotFoundException causing code is in one of Repository method -

Collection<FrameReference> dependenciesOfFrame(AssetId frameId) {

       Query referencesQuery = this.getSession().createNativeQuery(
                "SELECT a.asset_id as frame_id,  fr.name .... WHERE a.asset_id=:frameId"

        referencesQuery.setParameter("frameId", frameId.id());
        List<Object[]> frameIdsWithRefDetails = referencesQuery.list();

        Multimap<String, FrameReference> refDetailsByFrameId = convert(frameIdsWithRefDetails)
        Set<String> ids = refDetailsByFrameId.keySet();

        Query framesQuery = this.getSession().createQuery(
                    "from com.aginity.amp.catalogservice.domain.model.workspace.asset.frame.Frame as _obj_ "
                            + "where _obj_.assetId.id in (:ids)");

        framesQuery.setParameterList("ids", ids);
        Collection<Frame> frames = framesQuery.list(); // here is when exception occurs!


In either create or update frame flow it calls
to validate some business logic and after that it finally calls

I am stuck where the problem can be.
Maybe https://stackoverflow.com/questions/5512138/calling-hibernate-query-list-method-generates-errors is somehow related to my problem but I am nor sure.

Any ideas why the issue may occur?
