There seems to be a bug in the AspectJ compiler.
With your code as is, I see the same error, but there is also a warning ("-
inter-type constructor does not contain explicit constructor call: field
initializers in the target type will not be executed
[Xlint:noExplicitConstructorCall]". Then I modified the ITD declaration as
follows:
public Child.new(String name, int age) {
this(name);
super.getJob();//This seems to cause issues at runtime
}
The causes another error:
Exception in thread "main" java.lang.ClassCastException: java.lang.String
can not be converted to int
at org.aspectj.runtime.internal.Conversions.intValue(Conversions.java:57)
at example.Child.<init>(Parent.java:1)
at example.Main.main(Main.java:5)
BTW, my Main class is as follows:
public class Main {
public static void main(String[] args) {
new Child("myname", 5);
}
}
Can you file a bug so that it may be addressed? I am using the
1.7.3.20130613 version.
