Thanks for clarification, yeah, I will vote for upgrading our stack of dependencies.

That's imo the way to go. Not only are you working an standardized API, but you will benefit from other bug and performance fixes.

Additional reason for reporting this is that I didn't find anything about this issue.

Sure. I am glad you reported it. I am not going to close the issue for now. Maybe we stumble across the problem when doing another maintenance release or so. just saying, it won't be high priority.

The only I noticed is methodMetaData.getAllParameterMetaData() here doesn't contain any of constraints in parameter metadata in case when validation passes. And contains when validation works as expected.

ok
