Report from compiler-dev:

The following code does not compile:

import java.util.List;
import java.util.function.Predicate;

public class X<T> {
    public X(List<? extends T> l) {
    }
    void m(List<? extends String> list){
        X<String> boo3 = new X<>(findAll(list, s -> s.length() > 0)){};
    }

    static <T> List<T> findAll(List<? extends T> collection,
                               Predicate<? super T> condition) {
        return null;
    }
}

Problem goes back all the way to JDK9.

Error reported:

error: cannot find symbol
  symbol: class <captured wildcard>
  location: class X<T>
  where T is a type-variable:
    T extends Object declared in class X
