*Expected behavior*
I would like to mix hibernate search and envers together. The main goal would be to be able to audit my entity and to have a searchable projection of it using elasticsearch. I do not want to have a representation in elasticsearch of *_aud* tables and *DefaultRevisionEntity*.
*Current behavior*
I made a Quarkus POC to reproduce the current behavior.
The application fails to start due to an exception thrown at startup:

{ noformat code }
*To Reproduce*
Steps to reproduce the behavior:
1. git clone [ https://github.com/dcdh/poc-quarkus-persistence.git |https://github.com/dcdh/poc-quarkus-persistence.git]
2. checkout branch *search_with_auditing*
3. run the application using the script *run_dev.sh*
*Additional information*
The exception occurs because the auditable table is not associated with a JPA entity.
The impacted code is this one from the class *HibernateOrmBootstrapIntrospector* :
{ noformat code:java }
for ( PersistentClass persistentClass : persistentClasses ) {
collectEmbeddedTypesRecursively( typeMetadata, persistentClass.getIdentifier() );
collectEmbeddedTypesRecursively( typeMetadata, persistentClass.getPropertyIterator() );
}
{ noformat code }
The auditable tabe is considered as a persistentClasses and when the code will try to collect all embeded type recursively an exception will be thrown and the application will fail.
I notice that for an audited table the className property is null. Maybe that it could be a solution to filter and reject all table persistentClasses having a null className ? and add a special case (or not) regarding the *DefaultRevisionEntity* but it will introduce a high coupling with Envers...
