This is SpEL and our core ReflectionUtils being used as a tool here... The real culprit seems to be a Thymeleaf expression which tries to dereference HashMap.Node.key. In any case, this needs to be fixed on Thymeleaf's end or in the application code containing that expression; there is nothing we can about it on the core framework's end.
