Björn Kautler created GROOVY-9244:
-------------------------------------
Summary: Anonymous subclasses should cast their super-parameters
Key: GROOVY-9244
URL: https://issues.apache.org/jira/browse/GROOVY-9244
Project: Groovy
Issue Type: Bug
Affects Versions: 2.5.7, 2.4.7
Environment: I tried in GroovyConsole 2.4.7 and Groovy web console
2.5.7
Reporter: Björn Kautler
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 anc Groovy4 instantiation fail
Groovy5 and Groovy6 instantiation succeed and print {{String}}.
I did not found 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.
