bucket.user.DefaultUserAccessor.getMemberNames(com.atlassian.user.Group) returns stale result after bucket.user.DefaultUserAccessor.removeMembership(String, String)

The query for member names after the removal of a member from a group returns stale result (as if the member was not removed at all). This only occurs if:

• Membership removal and membership query of a group occurs within the same transaction (same Hibernate session).
• The group being modified has 3 or more members.

The repository being used is the OSUser repository.
