Description

Hello,

the code fails with the Exception on java 11.0.21 on groovy 3.0.18.

It works fine on groovy 3.0.17 or lower

import java.util.function.Function

class A {
    int a
}

class ToothChartContainerExtractionComparator implements Comparator<A> {

    @Override
    int compare(A a, A b) {
        comparing(typePriorityKeyExtractor).compare(a, b)
    }

    private static Function<A, Integer> typePriorityKeyExtractor = {it.a } as Function<A, Integer>

}

new ToothChartContainerExtractionComparator().compare(new A(), new A())
