Eric Milles resolved GROOVY-9857.
---------------------------------
    Fix Version/s: 4.0.7
       Resolution: Fixed

https://github.com/apache/groovy/commit/873e1952cf93373ad1eb348ef944fd628a3e9610

{{Immutable}} will not try and choose constructor.  You will however get an error now that there is no no-arg constructor to call and you must take some action.

> The transforms invoked by {{@Immutable}} generate constructor code that unconditionally makes a call to {{super()}} even when the superclass has no default constructor.
> {code:groovy}
> @TupleConstructor(defaults = false)
> abstract class AbstractClass {
>     String a
> }
> @Immutable
> class ImmutableSubclass extends AbstractClass {
>     String i
> }
> {code}
> Compiling this pair produces {{invokespecial AbstractClass.<init>()}}, which does not exist. This should at a minimum produce a compile-time error.
