The example had an unrelated compile error and didn't tell what was expected. Here's the fixed version:
package p;
import java.util.*;
public class C extends A {
public C(Map m) { // should warn about raw type m
super(m);
m.put("one", 1); // warns about raw method invocation (good)
}
public C(Map<String, Integer> m, boolean b) {
super(m); // shows that parametrizing the parameter type is no problem
new A(m);
m.put("one", 1);
}
}

HEAD COMPILER_PB_UNAVOIDABLE_GENERIC_TYPE_PROBLEMS wrongly suppresses problems for raw constructor parameter types. Even if a super constructor needs a raw type, a subclass can still parametrize its constructor. Here's an example to play with: package p; import java.util.Map; public class A { public A(Map m) { } } package p; import java.util.*; public class C extends A { public C(Map m) { super(m); m.put("one", 1); } public C(Map<String, String> m, boolean b) { super(m); // shows that parametrizing the parameter type is no problem new A(m); m.put("one", 1); } }
