b117: Self-reference in initializer does no longer work

See https://bugs.openjdk.java.net/browse/JDK-8024809

Basically a field cannot reference itself in the initializer, even if
the reference occurs inside a lambda expression.

However, you can bypass this kind of static analysis by using
`this.r`. If that doesn't work in some context (where javac equates
`this.r` and `r`) you can try `(this).r`.
