When a proxy bean (e.g., the child) is passed to another bean (e.g., the parent), and that bean tries to call a method inherited from Java Object (e.g. toString) we get an IllegalAccessException. The bean may be proxied because, for example, it has @transactional methods. This begun, I believe, when we upgraded Spring from 5.3.1 to 5.3.8, although I can’t be sure of this. We are currently using Spring 5.3.8 on Java 11.

In my case, overriding the toString method resolved the issue. This was very time consuming to track down, however. It would be nice if Spring could handle this better.

The following is debug output when run with --illegal-access=deny option.

This looks like the fundamental issue in #27490, addressed in 5.3.11. Could try your scenario against the recent 5.3.13 release?

Indeed, upgrading to 5.3.13 resolved the issue. Thank you for such a quick response! I am closing this.
