public class First {
  public static void main(String[] args) {
    System.out.println("Hello Java 11");
  }

上記のプログラムをJava 11 intellijで実行しようとしています。

Java 11はまだ非常に新しいです。

IntelliJのキャッシュが破損したのではないかと思うので、それらをクリアすると解決するはずです。

このような新しいJDKを使用する場合、Intellijも最新の状態に保ちます。

ここで同じエラーが発生し、intellij 2018.1にアップグレードされ、エラーはなくなりました。
