Access from multiple nested inner classes is incorrect

[Marcono1234]

CFR version

0.149-SNAPSHOT (commit 06539a4)

Description

When decompiling classes containing multiple nested inner classes which access the field of the enclosing class, the code generated by CFR is invalid:

A.this.NestedInnerClasses.this.str

Example code

public class NestedInnerClasses {
    private String str;
    
    class A {
        class B {
            String doSomething() {
                return str;
            }
        }
    }
}
