Hi Andrus, I've been taking a look at this with Maik, here's a runnable example project containing a commit that works on v4.1 but fails in v4.2:
https://github.com/hugithordarson/xx-c42/ Quick link to the code actually demonstrating the failure: https://github.com/hugithordarson/xx-c42/blob/main/src/main/java/family/Main.java The last commit certainly results in a circular reference being present in the object graph, but it probably shouldn't be a problem for the actual operation since we're only updating a single row, right?
