Compile the code below and execute Test. You get a stacktrace like the following:

Exception in thread "main" java.lang.ClassCastException: [LType;
        at SubWorker.doit(X.java:1)
        at Test.main(X.java:17)



class Type { }
class SubType extends Type { }
 
class Worker<T extends Type> {
    public void doit(T... ts) {}
}

class SubWorker extends Worker<SubType> {
	public void doit(SubType... ts) {}
}
 
class Test {
 
    public static void main(String args[]) {
        SubType s = new SubType();
        Worker<SubType> w = new SubWorker();
        w.doit(s,s);
        
        Worker<SubType> w2 = new Worker<SubType>();
        w2.doit(s,s);
    } 
}
