>                 Key: GROOVY-9244
>                 URL: https://issues.apache.org/jira/browse/GROOVY-9244
>             Project: Groovy
>          Issue Type: Bug
>    Affects Versions: 2.4.7, 2.5.7
>         Environment: I tried in GroovyConsole 2.4.7 and Groovy web console 2.5.7
>            Reporter: Björn Kautler
>            Assignee: Eric Milles
>            Priority: Major
>             Fix For: 2.5.9, 3.0.0-rc-1
>
>          Time Spent: 1h 40m
>  Remaining Estimate: 0h

> Given this code:
> {noformat}
>     import java.util.regex.Pattern
>     abstract class Groovy3 {
>         Groovy3(String s) { println "String" }
>         Groovy3(Pattern p) { println "Pattern" }
>     }
>     class Groovy4 extends Groovy3 {
>         Groovy4(String s) { super(s) }
>         Groovy4(Pattern p) { super(p) }
>     }
>     class Groovy5 extends Groovy3 {
>         Groovy5(String s) { super(s as String) }
>         Groovy5(Pattern p) { super(p as Pattern) }
>     }
>     class Groovy6 {
>         Groovy6(String s) { println "String" }
>         Groovy6(Pattern p) { println "Pattern" }
>     }
>     new Groovy3(null as String) { }
>     new Groovy4(null as String)
>     new Groovy5(null as String)
>     new Groovy6(null as String)
> {noformat}
> Groovy3ish and Groovy4 instantiation fail
> Groovy5 and Groovy6 instantiation succeed and print {{String}}.
> I did not find a way to make the Groovy3ish one work, except for doing it the Groovy4 way, but no chance with an anonymous subclass.
> From what I observed, I guess the anonymous subclass does it like Groovy4 but should do it like Groovy5 to properly select the super constructor.
