Entering the following code gives a warning icon in the LHS margin in 3.1M5:

interface Callable<T>
{
    public enum Result { GOOD, BAD };
    public Result call(T arg);
}

public class StaticExample implements Callable<String>
{
    public Result call(String arg) { return Result.GOOD; } // Warning line
}

The warning appears for the token "Result" on the line indicated. It reads "Type
safety: The return type Callable<String>.Result for call(String) from the type
StaticExample needs unchecked conversion to conform to Callable.Result from the
type Callable<T>."

However compiling this with "javac -Xlint StaticExample.java" gives no warnings.
