(bug?) - json path match assertion with wildcards 'select from current' results in failure

No, that wasn't the difference.

But that showed me in the right direction, so thank you AlexKaras .

It is actually the "allow wildcards" check that explains the behaviour. Nothing to do with the v2.8 vs 3.0, sorry for bringing that up. I never thought allowing wild cards would make the assertion fail. No valid reason for that in my view, so I guess it stays a bug :-)
