Bunch of errors when testing with SpringChallenge 2021 ref (java 16.0.1 on windows 10)

[NoRabbit]

I tried a couple of different things but didn't put my hands into the code (yet). I took the released jars on github and also tried with a local compiled version. Same thing. I just hope someone knows what this is about by just looking at those lines (I'm not familiar with java). Thx.

I have got same problem under Windows 10.

Brutaltester does not support java 16.

In fact, I have never tested brutaltester on a Java higher than 1.8.

Ok thx. Tested with java 1.8 and it works perfectly.
