      Description

      This class:

      public primitive class CheckRefLambda.val {
          int theInteger;
          public CheckRefLambda(int newValue) {
              theInteger = newValue;
          }
          public Supplier<CheckRefLambda.ref> makeCopier() {
              return () -> new CheckRefLambda(this.theInteger + 1);
          }
          // ...
      }

      won't bootstrap the lambda, but fails with:
