Could not analyze lambda code

[sysmat]

• org.jinq:jinq-jpa:1.8.30
• Using Pair

JinqJPAStreamProvider streams = new JinqJPAStreamProvider(factory);
JinqStream<AaiUser> usersStream = streams.streamAll(em, AaiUser.class);
List<Pair<Long, Date>> pairs = usersStream.select(u -> new Pair<>(u.id, u.created)).toList();

• I got run time error:

Jinq does not support entities that use field access. Jinq only supports using getters.
