Got NullPointerException при включении индекса поиска для Jackrabbit

Question

Я сейчас разрабатываю приложение, которое активно использует jackrabbit. Это мой первый опыт работы с jackrabbit. Я использую h2-конфигурацию для моих тестов junit. поиск Lucene был отключен в моей repository.xml и единственной проблемой было следующее исключение в файле журнала:

ERROR org.apache.jackrabbit.core.security.user.MembershipCache - Failed to retrieve membership references of 21232f29-7a57-35a7-8389-4a0e4a801fc3. 
javax.jcr.RepositoryException: no search manager configured for this workspace 

Все модульные тесты прошли. Когда я начал тестировать функциональность, которая использует UserManager.findAuthorizables, мне пришлось включить SearchIndex в файле repository.xml.
Теперь все мои тесты не с расстраивать NullPointerException:

Я занимаюсь и эта проблема на Jackrabbit 2.3.4. Я попытался использовать недавно выпущенный 2.4.0 - без успеха.
Кажется, что jackrabbit не может создать пользователей, перечисленных в разделе конфигурации LoginModule. Но почему? Что мне не хватает?

Answer 1

Моя ошибка.
Я проверил свой репозиторий плюща и обнаружил, что apache lucene был опубликован более новой версией 3.3.0. Jackrabbit в своем дистрибутиве использует lucene 3.0.3
Когда я опубликовал «тесты, основанные на« дружеских »тестах на lubene, стали проходить.
