Description Philipe Mulet CLA 2008-07-15 07:32:38 EDT 
3.4.0

Following code should yield an unchecked cast from List<Object> to Throwable.

import java.util.Collections;
public class X {
	X() {
		Throwable t = (Throwable) Collections.emptyList();
	}
}
Comment 1 Philipe Mulet CLA 2008-11-10 09:03:53 EST 
import java.util.*;
public class X {
    X(List rawList, List<?> unboundList) {
            Throwable t0 = (Throwable) Collections.emptyList(); // unchecked
            Throwable t1 = (Throwable) rawList; // no warn
            Throwable t2 = (Throwable) unboundList; // unchecked
    }
}

Released for 3.5M4.
Fixed
Comment 5 Philipe Mulet CLA 2008-12-02 04:54:40 EST 
After second thought, I don't think this one should be flagged as unchecked any longer.

Will back out the change.
Comment 6 Philipe Mulet CLA 2008-12-02 04:59:51 EST 
Backed out the change, and added more unchecked warning tests:
