Invalid method reference used for 'Comparator'
Reports method references mapped to the Comparator interface that don't fulfill its contract.
Some method references, like Integer::max, can be mapped to the Comparator interface. However, using them as Comparator is meaningless and the result might be unpredictable.
Example:
ArrayList<Integer> ints = foo();
ints.sort(Math::min);After the quick-fix is applied:
ArrayList<Integer> ints = foo();
ints.sort(Comparator.reverseOrder());- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
