RealmList is null in Java17

[ErnestoDavidOlivaPerez]

How frequently does the bug occur?

Always

Description

I have a two RealmObject's called ParentObject and ChildObject. ParentObject has a RealmList of type ChildObject. When I create a ParentOject and copy it to realm using Realm.createObject(), I expect the returned value to have an empty RealmList of type ChildObject, but I find that field is null. Investigating I looking that this happens when I use Java 17, with Java 11 does not return null.

I don't know why this is happening or if it is a deliberate behaviour. I would like to give answers to these doubts I have. To solve this problem I'm going to check if the RealmList field is null and if it is, create it, at least until I get an answer.

The error has been fixed. The next day when I went to find the problem again, I tried to do more test to find a solution or better understand what is happening. But I found that the problem had been solved. The only thing that I think could fix the problem is to clean the project. In any case I close the issue and leave my experience in case anyone needs it.
