Today I switched from HV 5.0.1 to 5.2.1 and happily enough to know that it was claimed to be a drop-in replacement for all 5.x versions, I started my code and WOW! My code throws NPE at our initial system validations with this stack trace:
Working a little bit on the issue, I could manage to reproduce it in a simple unit test that I've attached. I repeat it here for the sake of description.
Suppose that we have these simple classes:
If I want to validate an instance of MainBean which has an instance of BottomBean as its child, the mentioned exception occurs!
I searched the issue database to find that HV-975 Closed has already reported this same issue, but since there has been no test cases, the issue was resolved with "Cannot Reproduce". As I could not reopen the issue, I decided to report it here since I think it is a downside to a very reliable library.
