org.hibernate.search.exception.AssertionFailure: Unable to find service related to class org.hibernate.search.hcore.impl.MassIndexerFactoryProvider

Using ORM 4.3.11 and Search 4.5.3.Final on JDK 1.8.

Can someone translate?

Hey,
thanks for reaching out! It’s a bit hard to tell based on the info you’ve provided so far… are there any other errors/exceptions logged/thrown ?
that assertion can be thrown if something released the MassIndexerFactoryProvider service other than that finally block:

github.com/hibernate/hibernate-search

orm/src/main/java/org/hibernate/search/impl/FullTextSessionImpl.java

e6f3ff107


      
          	public MassIndexer createIndexer(Class<?>... types) {
          		//We shouldn't expose the ServiceManager in phases other than startup or teardown, that's why the cast is required.
          		//Exceptionally, this very specific case is fine. TODO: cleanup this mess.
          		MutableSearchFactory msf = (MutableSearchFactory) getSearchFactoryImplementor();
          		ServiceManager serviceManager = msf.getServiceManager();
          		MassIndexerFactory service = serviceManager.requestService( MassIndexerFactoryProvider.class, null );
          		try {
          			return service.createMassIndexer( getSearchFactoryImplementor(), getFactory(), types );
          		}
          		finally {
          			serviceManager.releaseService( MassIndexerFactoryProvider.class );
          		}

but hard to tell without a reproducer , also note that 4.x is a pretty outdated version which is out of support…

I think the problem is they configured the data source with transactions instead of manual.
