Eric Milles updated GROOVY-9168:
--------------------------------
Comment: was deleted
(was: The Runnable case compiles and runs fine in java. The enclosing method
for the AIC must be static initializer or something.
Here is the complete Java example:
{code:java}
public class Runner {
public static void main(String[] args) {
new Runner();
}
public Runner() {
this(new Runnable() {
@Override public void run() {
System.out.println("ran");
}
});
}
public Runner(Runnable action) {
action.run();
}
}
{code}
{code}
// Method descriptor #15 ()V
// Stack: 3, Locals: 1
public Runner();
0 aload_0 [this]
1 new Runner$1 [3]
4 dup
5 invokespecial Runner$1() [4]
8 invokespecial Runner(java.lang.Runnable) [5]
11 return

> Key: GROOVY-9168
> URL: https://issues.apache.org/jira/browse/GROOVY-9168
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 3.0.0-beta-1, 2.5.7
> Reporter: Eric Milles
> Priority: Major
>
> This is a variation of GROOVY-6777, GROOVY-6809 and GROOVY-7609. A
> constructor's parameter may not presently be defaulted by a value expression
> using a non-static inner class (including anon. inner). This is likely
> caused by the uninitialized "this" reference that is supplied to the
> constructor of the non-static inner class.
> {code:groovy}
> // Error: Apparent variable 'this' was found in a static scope but doesn't
> refer to a local variable, static field or class.
> class Outer {
> class Inner {} // make this static and all is well
> Outer(Inner inner = new Inner()) {
> }
> }
> new Outer()
> {code}
> {code:groovy}
> class C {
> C(Runnable runner = new Runnable() { void run() {} }) {
> // ^^^^^^^^^^^^^^ enclosing method not set and ...
> this.runner = runner
> }
> Runnable runner
> }
> new C().runner.run()
> {code}
