Let's consider following code:

class List<T> {
}

public class Test26 {
    public static <T> List<T> m(List<T> list, T item) {
        return list;
    }
    public static void run() {
        m(new List<FooOuter.Foo<String>>(), new FooOuter().new Foo<>(){ });
    }
}

class FooOuter {
    class Foo<T> {
        public Foo(){
        }
    }
}

it causes compilation internal error on JDK9b75:

An exception has occurred in the compiler (1.9.0-ea). Please file a bug at the Java Bug Database (http://bugreport.java.com/bugreport/) after checking the database for duplicates. Include your program

It looks like JDK-8132535, but the error thrown by javac is different.
