Bug in connecting objects #2318
Description
It seems that there is something wrong which causes this code to behave nondeterministically and sometimes wrong.
final C c = new C("att");
final B b = new B(List.of(new B.C2(c)));
final A a = new A(List.of(c), List.of(b));
a.getCs().forEach(definition -> template.save(definition));
a.getBs().forEach(definition -> template.save(definition));
template.save(a);
final Optional<Map<String, Object>> one = client.query("Match (n{id:'att'})-[r]-(m:A) return count(r)").fetch().one();
System.out.println(one.get().get("count(r)"));
a has a member cs which includes a C object. However, sometimes a link is created between a and c (thus, printing 1) and sometimes no link is created between them (thus, printing 0).
Just run the code several times and see what is printed.
