Invalid result rows when ManyToMany "fetch joined" with additional child OneToMany or ManyToMany child relationship fetched

[rbygrave]

So where "level2s" is a ManyToMany with "level2s.level3s" as a OneToMany or ManyToMany ... and there is a prior OneToMany or ManyToMany (in the case below "level4s") so that the level2s are fetched as a "fetch join" (not part of the origin query).

... then the level2s (ManyToMany) are not loaded/associated correctly against the root object.

        final List<Level1x> things = Ebean.find(Level1x.class)
                .fetch("level4s")
                .fetch("level2s")
                .fetch("level2s.level3s")
                .order().asc("id")
                .findList();
