[Resolvido] DB4O Erro ao efetuar commit da "sessão"

Assuntos Gerais
#1

Comecei a fazer testes com o db4o, porém estou tendo problemas relacionados à utilização de sessões a partir do container principal.
Ocorre o erro Objects must not be updated in callback ao tentar efetuar commit da sessão.

ObjectContainer container = Db4oEmbedded.openFile(
		configuracao(), 
		new StringBuilder(CAMINHO_BASE_LOCAL).append(base.nomeLocal()).toString()
);

ObjectContainer session = container.ext().openSession();
		
try {
	
	if (session.query(IdEfd.class).size() == 0) 
		session.store(new IdEfd());
	
	session.commit();

} catch (Exception e) {
	session.rollback();
	e.printStackTrace();
} finally {
	container.close();
}
