I tried in GroovyConsole 2.4.7 and Groovy web console 2.5.7
Description
Given this code:
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)
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.
