URL: https://issues.apache.org/jira/browse/CAY-1695

For example you have User and UserInfo entities. User has one-to-one relationship with UserInfo. If you try to do select for User with prefetching on userInfo and userInfo.user, you will get null value for userInfo property:
SelectQuery query = new SelectQuery(User.class);
query.addPrefetch("userInfo");
query.addPrefetch("userInfo.user");
It doest meter which kind of prefetching do you use.
