[BUG] lombok.val causes compilation failure when used with default implementation of an interface method

[phommy]

Describe the bug
"mvn clean compile" will throw an error if, in a method, there is both a variable declared with lombok.val and a call to the default implementation of a interface

To Reproduce

package com.example;

import lombok.val;

public class class1 implements interface1 {
    void method1() {
        // If you comment any of the following two lines, the project compiles normally.
        // Otherwise, "mvn clean compile" will report the following error:
        // Compilation failure
        // Lombok visitor handler class lombok.javac.handlers.HandleVal failed:
        // java.lang.AssertionError

        val string1 = "s";
        interface1.super.defaultMethod();
    }
}

public interface interface1 {
    default void defaultMethod() {
    }
}
