Description

I have build a subclass of java.lang.Exception which calls the super constructor of Exception with a String parameter.
When instanciating the class I get an class cast error.

class ExceptionSubclass extends Exception {
ExceptionSubclass(String s)

{ super(s) }
public static void main(String[] args) { println new ExceptionSubclass("s") }
}

I get the error: Caught: java.lang.ClassCastException: java.lang.String


If I create a java helper class which is a subclass of Exception everything works find:

public class JavaException extends Exception { //Java
public JavaException(String s) { super(s);}
}

class ExceptionSubclass extends JavaException { // Groovy
ExceptionSubclass(String s) { super(s) }

public static void main(String[] args)

{ println new ExceptionSubclass("s") }

}
