Hi
For some reason, the mailing server included only the first
attachment. Since this is the fourth or the fifth time I am trying to
send the java files, I give up. I'll inline them in the message.
// src/test/Base.java
package test;
public class Base {}
// src/test/Sub.java
package test;
public class Sub extends Base {}
// src/test/Test1.java
package test;
public class Test1<T extends Base> {
public class Inner1 {
protected T v;
public Inner1(T v) {this.v = v;}
public T getV() {return this.v;}
}
public Inner1 getInner(T v) {return new Inner1(v);}
}
// src/test/Test2.java
package test;
public class Test2<T extends Base> extends Test1<T> {
public class Inner2 extends Inner1 {
public Inner2(T v) {super(v);}
//public T getV() {return this.v;}
}
}
// src/test/Test3.java
package test;
public class Test3 extends Test2<Sub> {
public class Inner3 extends Inner2 {
public Inner3(Sub v) {super(v);}
public Sub p() {return this.getV();}
}
public Inner3 g() {
return new Inner3(new Sub());
}
}
HTH,

I must admit that this behaviour is really strange. I am interested in
helping you but the problem is that I didn't receive any .java files. Please
try to prvide them again.
Initially, I thought that this was a problem with the Java compiler.
