   Reproducing on the latest main

   with different Lambda usages

       Integer supplier(Supplier<Integer> supplier) {
           return supplier.get() * supplier.get();
       }
   
       Integer useSupplier(int i) {
           return supplier(() -> i * new Random().nextInt());
       }
   
       Function<Integer, Integer> function = integer -> integer * integer;
   
       Integer useFunction(int i) {
           return function.apply(i);
       }

   The following exception is thrown by Concrete Executor:
