Error "class file version 0.0) was compiled with an invalid major version"

[Danghor]

For unknown reasons, the grader produces the error message "class file version 0.0) was compiled with an invalid major version" when running the graderPrivaterRun Task.

Can be repdroduced in branch https://github.com/FOP-2223/FOP-2223-H08-Root/tree/grader at least in commit b852be20ad3b5e5495d4008085b5f49b682e7b58

Workaround: remove second transformer in RubricProvider, i.e. comment out configuration.addTransformer(new ArrayCalculatorCtorReplacer());
