无法获得实现扩展另一个接口进行编译的接口的Java枚举

Dog*_*Dog 1 java enums compiler-bug

我想创建一个实现的枚举I2,它扩展了I1:

package a;

import static a.E1.E1A;
interface I1 extends I1 {}
interface I2 extends I1 {}
enum E1 implements I2 { E1A, A1B; }

class A {
    public static void main(String[] args) {
        switch (E1A) {
            case E1A:
                System.out.println("it worked!");
        }
    }
}
Run Code Online (Sandbox Code Playgroud)

它一直在工作,直到我添加I1并I2扩展I1.现在它可以工作,但它找不到E1A(之前的静态存在,所以这不是问题):

$ javac A.java
A.java:3: cannot find symbol
symbol  : static E1A
location: class a.E1
import static a.E1.E1A;
^
