Description Igor Fedorenko CLA 2004-11-15 00:04:28 EST 
Eclipse 3.1 200411101000 does not warn about the following unchecked cast 

======
package test.cheetah;
import java.util.List;
public class Test<T> {
    List<T> list;
    void add(Object abs) {
        list.add((T) abs); // unchecked cast
    }
}
======
Comment 1 Philipe Mulet CLA 2004-12-16 17:14:18 EST 
Added support to detect unsafe cast to type variable.
Added regression test: GenericTypeTest#test438.
Also tuned unsafe cast message to read:

1. WARNING in d:\...\src\X.java (at line 6)
	list.add((T) abs); // unchecked cast
	         ^^^^^^^
Type safety: The cast from Object to T will actually check against the erased
type Object at runtime
