The declared return type of Hazelcast session repository bean factory method (i.e. HazelcastHttpSessionConfiguration#sessionRepository) was changed to SessionRepository<?> when support for Hazelcast 4 was added. This breaks Spring Boot's ability to auto-configure sessions endpoint, which is @ConditionalOnBean(FindByIndexNameSessionRepository.class), as the current return type is not specific enough to satisfy this condition.
This commit changes the return type of Hazelcast session repository bean factory method to FindByIndexNameSessionRepository<?>.
Closes: gh-1906
