Isolation level is always null, if queried from the RepositoryConnection #4802

Hi there,
I had a problem with concurrent transactions, so I wanted to log the isolation level of the current connection using RepositoryConnection#getIsolationLevel method. However it always returns null. The underlying sailConnection property of the SailRepositoryConnection shows the set isolation level. Is this intended?
I am a bit confused about this. Here is a short reproducer:
import org.eclipse.rdf4j.common.transaction.IsolationLevels;
import org.eclipse.rdf4j.repository.Repository;
import org.eclipse.rdf4j.repository.RepositoryConnection;
import org.eclipse.rdf4j.repository.sail.SailRepository;
import org.eclipse.rdf4j.sail.memory.MemoryStore;
class Scratch {
public static void main(String[] args) {
Repository sailRepository = new SailRepository(new MemoryStore());
try (RepositoryConnection connection = sailRepository.getConnection()) {
connection.begin(IsolationLevels.SERIALIZABLE);
System.out.println(connection.getIsolationLevel());
connection.commit();
}
}
}Edit: Screenshot of the debugger window attached
